The Trek Fuel EX 9.9 X0 AXS T-Type – In our big 2024 trail bike group test

The latest rendition of a true classic. With the Fuel EX 9.9 X0 AXS T-Type, the American manufacturer introduces the latest generation of their trail veteran, which is intended to cover an even wider range of ​​applications, and can be perfectly adapted to your needs with many adjustment options. How does the concept work in practice?

The Trek Fuel EX 9.9 X0 AXS T-Type was conceived as a potent trail bike with a top-tier spec. It generates more travel than its predecessor, combining 150/140 mm at the front and rear, respectively. Retailing at € 9,499, the Fuel EX tips the scales at 14.9 kg and looks a lot like its electric counterpart, the Fuel EXe , which has already proven what it’s capable of in our light eMTB comparison test. The analogue Fuel EX model is available in seven sizes and offers countless adjustment options, both for the geometry and kinematics, making it an incredibly versatile bike.

The 2023 Trek Fuel EX 9.9 X0 AXS T-Type in detail

With its unmistakable frame silhouette and vertically-mounted shock, the Fuel EX 9.9 X0 AXS T-Type is distinctly recognisable as a Trek. The proprietary Active Braking Pivot rear suspension positions the rear axle inside the rear pivot bearing, which is meant to reduce the impact of braking on suspension performance. As usual, the cables are routed internally, running through the frame inside a sleeve, which makes it easier to work on the bike and replace the cables. The cables aren’t clamped at the ports, but don’t rattle on the trail. However, the brake line of the rear SRAM CODE Stealth brake slams against the handlebars and can’t be secured to the one-piece handlebar. A generously sized TPU ⁠plate on the down tube protects the frame against impacts and is complemented by an extensive chainstay protector. That said, when landing big drops and ploughing through rough trail sections, you can still hear the chain slapping against the frame. Of course, there’s also a storage compartment in the down tube – Trek were amongst the pioneers of on-bike stowage systems! The closure system is easy to use and seals tightly. The storage compartment comes standard with a small pouch where you can securely store all your trail essentials . Trek also hide a Bontrager multi-tool inside the steerer tube, which includes all of the basic tools for essential trailside repairs. Unfortunately, the tool makes a faint rattling noise on the trail, and while it’s not too bad, you still know that it’s there.

The spec of the 2023 Trek Fuel EX 9.9 X0 AXS T-Type

The Fuel EX 9.9 X0 AXS T-Type might not be the flagship model in the Fuel EX range, but it has a top spec. The FOX Factory suspension consists of a 36 mm GRIP2 fork and standard FLOAT X shock, which supercedes Trek’s proprietary Thru Shaft shock found on older previous models. The cables are routed internally, and run through the frame inside guide sleeves, which makes it easier to service the bike and replace the cables. The wireless, 170 mm RockShox Reverb AXS dropper post ensures lightning fast, butter smooth action. The American component colossus also supplies the CODE Silver Stealth brakes with tool-free bite point and lever reach adjustments. The levers also feature SRAM’s proprietary SwingLink technology, which was designed to minimise deadband and optimise modulation, thus reducing arm pump. The brakes are effectively identical to the Ultimate flagship model except for the carbon levers, and paired with a 200 mm rotor at the front and 180 mm disc at the rear. We would recommend upgrading to a 200 rotor at the rear to improve braking performance and modulation. The SRAM X0 Transmission rear derailleur is attached directly to the frame, forgoing both a mech hanger and the limit screws. Trek’s in-house, one-piece Bontrager RSL one-piece carbon cockpit consists of a 50 mm stem and 820 mm handlebars. These are far too wide, so we recommend cutting them to size. Moreover, the one-piece design doesn’t allow for fine tuning, except for the stack height, which can be adjusted with conventional round spacers – the cockpit on the SCOTT doesn’t even allow you to do that, with its proprietary spacers. The Fuel EX rolls on a Bontrager Line Pro 30 wheelset and Bontrager SE5 Team Issue tires front and rear, which are a perfect match for the bike’s intended use, providing predictable, controlled handling and adequate puncture protection.

How would you like it? The Trek is available in countless frame sizes and offers many adjustment options.

The geometry of the 2023 Trek Fuel EX

The Trek Fuel EX is available in a whopping seven, sizes XS to XXL, which includes an intermediate ML size. Reach values change in smaller intervals between sizes M, ML and L, which makes it easier to choose your frame size if you’re sitting on the fence. The smallest XS frame rolls on 27.5″ wheels and with size S you can choose between 27.5″ and 29″, while all other frames come standard with 29” wheels. The Fuel EX also features three different geometry adjustments: the Mino Link, which is essentially a flip chip in the seat stay, lets you switch between a high and a low setting. Another flip chip in the lower shock mount changes the rear suspension’s progression, making it compatible with a coil shock. Moreover, you can change the head tube angle between three different settings using different headset cups that can be purchased separately. If you fancy a mullet bike, the Fuel EX is a great option, as it can be converted to a mixed-wheel setup using a 160 mm fork and the low geometry setting. We mainly rode the bike in the low setting, with progressive rear suspension. Chainstay length is a moderate 440 mm in size L and grows with the frame size, with four different lengths serving the 7 different frame sizes.

The 2023 Trek Fuel EX 9.9 X0 AXS T-Type on the trail

When riding uphill, the Trek Fuel EX 9.9 X0 AXS T-Type places you in a comfortable, upright pedalling position, with the weight evenly distributed between the front and rear. However, on steep climbs, the front end becomes a little light, forcing you to actively weight the front wheel to keep it tracking. The suspension bobs noticeably, and as a result, climbs are more of a means to an end for the Trek, which doesn’t feel as lively as some of its competitors. On long, monotonous climbs, we recommend reaching for the climb switch to kill the pogo stick effect and get to the trailhead more efficiently.

On the trail, the Fuel EX impresses with predictable, balanced handling and strikes an excellent balance between agility and composure.

When gravity takes over, the Trek Fuel EX makes you feel at ease from the get-go, responding to steering inputs eagerly without feeling too nervous. The suspension is one of the Fuel EX’s true strengths, working discreetly in the background while simultaneously doing exactly what you want it to, without any unpleasant surprises. Even in the progressive setting with an air shock, the suspension responds sensitively and generates good traction, while at the same time providing plenty of support in the mid-stroke, allowing you to generate speed by pumping through flow trails and providing enough reserves to bail you out of botched landings without bottoming out. All in all, the Trek is very composed, providing a similar degree of stability as the Santa Cruz and Cannondale – though struggling to keep up with them in terms of agility. This becomes evident particularly in tight corners, where the Trek feels a little cumbersome – shortening the handlebars would help significantly here. Nevertheless, the Fuel EX is a strong all-rounder that performs well on a variety of trails and strikes a great balance between agility and composure.

Who should take a closer look at the 2023 Trek Fuel EX 9.9 X0 AXS T-Type?

The intuitive handling and excellent rear suspension make the Trek Fuel EX 9.9 X0 AXS T-Type suitable for a wide range of trails and riders. With its many geometry and kinematics adjustments, it’s also a good choice for those riders who love to play around with different setups to find their sweet spot. It’s easy and intuitive to ride, and delivers outstanding trail performance, whether you’re a beginner or seasoned trail veteran. The harmonious overall package is rounded off with clever frame details, like the well-designed storage compartment and integrated minitool.

FIRST RIDE REVIEW

The new trek fuel ex review.

Photos & Words by Dario DiGiulio

As mountain biking has evolved into what it is today, the trails we ride on have slowly but surely raised the bar of what modern bikes have to keep up with. Sure, some tracks have been sanitized over time, but there’s no question that the pointy end of the sport has kept pushing forward. As a result, trail bikes have had to pick up the pace to match the expectations of the average rider, leading to more capable and confident rigs with every new model. Stepping up to the plate, we have the evolved version of the Trek Fuel EX, Trek’s mainstay trail bike. This time it’s really meant to do it all, riding anywhere and doing anything. Being this adaptable can be a tricky task though, so has Trek painted themselves into a corner?

The new Trek Fuel EX breaks just about every mold that the prior generations had fit into, with a full-on redesign for the new model. The name of the game here is adaptability, whether in the geometry, the suspension kinematics, or even what size wheels you’ll run. Thanks to their Mino Link flip chip and two sets of press-in headset cups, you can shift the character of this bike drastically to suit your terrain and preference. As a result, it’s a bit hard to parse out the specific geometry of the bike (however Trek’s site features a geometry tool to let you do so), so I’ll just speak to it in its most neutral form, which is where many will likely settle. There are a whopping 8 size variations to this bike from XS to XXL, so it’s worth digging through the geometry tables to see which might suit you best. They’re all sporting 140mm of rear travel with a 150mm fork, upping the numbers on the prior generation by 10mm.

I’ve been testing the large frame, which puts the reach and stack at around 485mm and 621mm, which are in line with the majority of the industry right now. In keeping with the new Trek Fuel EX’s theme of being adaptable and capable. In its neutral-low setting, the bike comes with a 64.5-degree head tube angle and the effective seat tube angle sits at 77.2-degrees. Chainstays shift with the frame size, and on a large come in at 440mm. Thanks to the Mino Link flip chip, you can adjust bottom bracket height by 8mm up from the slammed 38mm drop in stock configuration, with a 0.6° steeper head tube and seat tube angle. The more significant head tube adjustment comes from the independent press-in headset cups that Trek supplies, which can steepen or slacken things by a full degree, giving a very wide range of handling characteristics. The last frame toggle is the progression flip chip, offering a simple more or less option to tailor the suspension feel and offer uncompromised coil shock compatibility.

As is trend right now, you can set the Fuel Ex up as a mullet, simply by popping a 27.5” wheel in the rear, swapping the Mino Link to high mode, and bumping up fork travel to 160mm. The bike comes stock as a 29er front and rear (or 27.5″ in XS and Small), so you’ll have to make this change on your own accord.

A notable thing lacking from the newest Fuel EX its the Knock Block – you’ll find no such thing on this frame. X-up fans take note, as this is a big move for the engineers in Waterloo, Wisconsin, and was necessary to achieve the headset adjustment range they wanted. Trek has also moved away from the RE:aktiv damper shock, now simply relying on an off-the-shelf model. Still included in the frames are the handy-dandy stash box in the down tube, with what I think might be the best weather sealing of any of the options on the market at this point, and a neat BITS tool roll.

Build kits come in as many flavors as the sizes, and the range of options is quite extensive, beginning at a respectable $3,699. I’ve been on the highest end build, the 9.9 AXS especial, coming in at a healthy $10,749. From Bontrager Line 30 carbon wheels, to the RSL one-piece carbon cockpit, to the XX1 drivetrain, just about everything is as nice as it gets, as you’d hope for this kind of money.

At my height of 6’3”, the geo combination of the Neutral-Low-More flip chip configuration on the large size makes for a really comfortable fit,  one that feels stable enough at speed while still remaining lively for your average trail. I started my time testing the bright yellow Trek up in Whistler, riding some gnarly rocky pedal-access trails around the Valley. This was a great context for deciding where I stood on the less or more progression debate, and I settled on the latter end of the spectrum. Increased bottom-out resistance and a more supple top of travel were worth a slightly punchier suspension feel, and I stand by that choice for most of the riding I have around me. On my home trails in Bellingham, the Fuel has been a choice companion for fast and fun rides in our local trail systems, where technical and engaging climbs lead to fast, rooty, and jump-filled descents. My general synopsis is that this is a bike that loves to ride fast, both up and down.

The climbing characteristics are comfortable and neutral, without wallowing too much or lacking grip in trickier terrain. Like many of the take-aways of the bike as it comes stock, things are extra-medium, in the best way. Compared to the new Hightower, the bike has slightly less support, but is significantly better in rough terrain and successive hits. Compared to the Stumpjumper EVO, the Fuel EX is definitely more of a trail bike, less of the all-mountain enduro-lite ride that the Specialized offers. All three bikes serve as a nice gradient from the lighter and sportier end of the trail spectrum to the burlier and more capable side of the category. Sitting pretty right in the middle is the Fuel EX, but I’m sure one could tweak it to either of the other extremes, given how much variability is baked into this frame.

Build kit notes are mostly positive, which you’d hope to see from the highest end build. My main gripe is with the Bontrager SE5 tires, which are some the least confidence-inspiring I’ve ridden in recent memory. The casing and tread pattern are fine, but the compound doesn’t seem to want to hook up anywhere, whether it’s dry loose terrain, rock slabs, and especially wet roots. This would be an immediate swap in my book, and I’d just keep the stock tires to run in the rear when conditions are dry and beat at the peak of summer.

The removable shuttle pad doesn’t seem to want to stay close to the frame, and bows out slightly when attached, giving the downtime a funny bulged look to it. One other frame annoyance has been a recurring suspension knock, despite chasing through every bolt in the linkage with a torque wrench. I still have yet to find the culprit, but luckily it’s not very noticeable when riding.

As a system, I’ve been more than impressed by Trek’s work on the new Fuel EX. Not only does it feel quick and confidant in the stock configuration, it also offers a whole host of layout options to better cater the bike to your preferences.

THE WOLF’S FIRST IMPRESSION

To close out our review of the new Trek Fuel Ex, it’s clear that Trek’s engineers and designers set out to design a bike that caters to that wide center of the market – the trail bike – where most riders spend their time, and where a bike can take many forms. In that goal, they found success. Sure some riders may feel the new Fuel EX has departed from what they were used to and liked about the bike, but many other riders will likely welcome the advancements in capability and confidence on the trail. The Fuel EX is a highly adaptable bike that feels comfortable in a really wide variety of terrain but doesn’t confuse itself for anything more or less. Bike riders, rejoice.

Wil reviews the Trek Fuel EX 2023

Having undergone a ground-up redesign for 2023, the Trek Fuel EX has entered its burliest and biggest travel form yet. This latest model represents the 6th generation of Trek’s popular mid-travel trail bike, with the original having debuted all the way back in 2005. Trail riding has evolved a lot since then, and the new Fuel EX aims to keep up with that evolution by incorporating almost every mod-con you can think of.

Of course it’s big news whenever Trek releases a new Fuel EX, and given how important this bike is for the US brand, we were curious to see how the raft of updates would play out on the trail. We had a bit of an idea, having thoroughly enjoyed riding the electrified Trek Fuel EXe over the past few months. Would the muscle-powered version deliver the same good vibes? And how would it compare to the previous models that have given us so many fond riding memories over the years? We’ve been putting the Trek Fuel EX 2023 to the test to find out!

Watch our video review of the Trek Fuel EX 2023:

Along with the downtube storage, generous frame armour and size-specific chainstays, the Fuel EX appears to pack in almost everything you could possibly want in a modern trail bike.

An overview of the Trek Fuel EX 2023

For 2023, the Trek Fuel EX is built around an entirely new frame that’s produced in carbon and alloy variants. Suspension travel has increased by 10mm at both ends, with the new Fuel EX now sporting a 150mm fork and 140mm of rear travel via the ABP four-bar suspension design.

It’s worth noting that the frame will handle a 160mm travel fork, and thanks to the two-position Mino Link, it can also be run as a mullet. Borrowed from the Session downhill bike, there’s a two-position flip chip at the lower shock mount that offers linear and progressive settings. The latter option is what makes the new Fuel EX coil shock compatible.

On top of that, Trek will be offering aftermarket headset cups to steepen or slacken the head angle by a degree. Along with the downtube storage, generous frame armour and size-specific chainstays, the Fuel EX appears to pack in almost everything you could possibly want in a modern trail bike. It’s certainly an appealing package on paper, and one that’s ready to take on contemporaries like the Specialized Stumpjumper , Merida One-Forty , Canyon Spectral and Giant Trance X .

Trek Fuel EX price & specs

There are a number of different models available in the Trek Fuel EX 2023 lineup, though availability will vary depending on where you are in the world.

In Australia, prices currently range from $4,999 AUD for the Fuel EX 7, and go up to $8,999 AUD for the Fuel EX 9.8 XT model. The cheapest option is actually the Fuel EX 5, though that model carries over the previous generation frame. For a closer look at the specs, prices and all the new details, check out our Trek Fuel EX 2023 overview article for more.

Here we’ll be diving into our experience of testing the Trek Fuel EX 9.9 XX1 AXS model, which will be available in Australia in limited quantities through the custom Project One bike builder. It’s a media bike that was provided to us by Trek, and of course it comes dripping with lots of gold, carbon and wireless bits. However, as usual with our reviews, we won’t be going into detail about the Gucci-level spec. Instead, we’ll be concentrating on the important aspects that are shared throughout the Fuel EX lineup; the frame design, suspension performance and its on-trail handling.

The chassis feels near-bombproof, and combined with the supportive suspension, powerful brakes and high volume rubber, you’re served up plenty of confidence for pushing the front wheel into steep chutes and over technical A-lines.

Trek Fuel EX size & geometry

From X-Small through to XX-Large, the Trek Fuel EX is produced in no fewer than seven different sizes. Seven! Given that many brands only offer four or sometimes even just three frame sizes, that’s impressive.

The two smallest sizes feature 27.5in wheels, while the Medium and above come standard with 29in wheels. The Small is the only option that is available in either wheelsize.

At 175cm tall I’ve been riding a Medium, which features a 450mm reach. Thanks to the use of short seat tubes, a rider of my height could easily upsize to the M/L size to get a longer 470mm reach. Personally, I’ve found the fit of the Medium to be spot-on.

As for geometry, the Fuel EX features a 64.5° head angle and approximately a 77.5° effective seat tube angle in its stock configuration. The rear centre length varies between sizes, going up to 450mm on the largest frame. On the Medium I’ve been riding, the rear centre is a compact 435mm.

Coming off the Fuel EXe, I found it easy to settle into the Fuel EX. The only modification I needed to perform was to chop the comically wide handlebars from 820mm down to a more reasonable 780mm.

Suspension & tyre setup

Getting the Fuel EX set up is made easy thanks to Trek’s detailed online suspension calculator . Input the bike model and your riding weight, and out spits suggested air pressure and rebound settings for both the fork and shock. It even suggests tyre pressures, giving you a good place to start before hitting the trail. When brands like Canyon struggle to provide any recommendations at all, Trek should be commended for helping riders to get the most out of their bike.

For my 68kg riding weight, Trek suggests setting up the Fox 36 fork slightly softer and slower than usual. Recommended rear shock sag is 29%, and the calculator’s suggestion of 158psi got me to exactly that figure. Initially I set the rebound at 6/15 clicks as recommended, but while everything felt quite balanced front to back, the suspension was a little sluggish and duller than I wanted. Speeding up the rebound by a couple of clicks in both the fork and shock helped to make the whole bike feel a bit more lively, while improving small-bump reactivity.

Although the Bontrager SE5 tyres feature reinforced Core Strength casings, I still fitted a CushCore Pro insert to provide some additional pinch-flat protection and insurance for the carbon rims. Tyre pressures were set as per Trek’s recommendations with 20psi in the front and 22psi in the rear.

Trek Fuel EX weight

Confirmed weight for our Trek Fuel EX test bike is 14.4kg. That’s with the tyres set up tubeless, but without the CushCore insert or pedals.

It’s on the heavier side for a high-end carbon trail bike, though the 2.5in tyres, stocky carbon wheels and AXS components aren’t exactly the lightest going. Of course weights do vary throughout the Fuel EX lineup depending on the spec, and you can see the weights for all the different models in our range overview .

A contributing factor to the overall weight is the new frame, which has gained almost 700g over its predecessor. Trek claims the carbon frame weighs 3.4kg with the rear shock, making it a bit of a porker alongside some of the competition;

• Scott Genius HMX Carbon: 2,249g
• Specialized Stumpjumper Carbon: 2,280g
• Giant Trance X Advanced Pro 29: 2,498g
• Specialized Stumpjumper EVO Carbon: 2,750g
• Canyon Spectral CF: 3,047g
• Trek Fuel EX Carbon: 3,400g

The new alloy Fuel EX frame is heavier again, coming in at a hefty 4.6kg with shock.

Of course weight isn’t everything, and it’s unsurprising that the new frame has gotten heavier given how much longer and slacker it is. Still, for those who are especially concerned by grams, there are certainly lighter options on the market.

What do we dig about the Trek Fuel EX 2023?

With its added heft and updated geometry, the Trek Fuel EX 2023 is no doubt the burliest iteration yet. The chassis feels near-bombproof, and combined with the supportive suspension, powerful brakes and high volume rubber, you’re served up plenty of confidence for pushing the front wheel into steep chutes and over technical A-lines.

Indeed it’s massively capable for a 140mm travel bike, with the slack 64.5° head angle and roomy wheelbase giving it a purposeful stance on the trail. The geometry is superb, with welcome updates that have brought the Fuel EX right up to speed.

The steeper seat angle is particularly noticeable over the old bike, providing a much improved seated position on steep climbs. Pedalling efficiency has also levelled up. Trek has lifted the main pivot above the chainring to increase anti-squat, which helps to reduce pedal-induced bobbing. The Float X shock has a two-position climb switch, but I never once needed to use it while riding off-road since the rear end is so well behaved.

It rips through the turns

Once up to speed on flower singletrack, the taut chassis means the Trek Fuel EX is highly responsive when rounding corners and pushing into berms.

With its boxy downtube, split top tube and the supporting strut for the lower shock mount, the front triangle is heavily braced to resist torsional flex. Along with the wide main pivot and boxy one-piece chainstays, the Fuel EX possesses a strong spine from its shapely head tube to the rear thru-axle. The muscly frame effectively translates handling inputs while resisting lateral deflection through the turns.

Likewise, the short rear end and generous 38mm BB drop are fantastic when threading your way through twisty sections of trail, keeping you connected to the terrain and contributing to the playful ride quality. The low-hanging BB did mean I caught the pedals occasionally, so those who frequent off-piste terrain and technical climbs will want to consider flipping the Mino Link into the High position to indulge in an extra 7mm of pedal clearance.

Otherwise the riding position and weight distribution are totally sorted. The handling is approachable, and the Fuel EX doesn’t demand a whole lot from you as the rider. Compared to the old bike it does need a more concerted lean when entering tighter corners, though this is a part of the natural evolution of modern trail bike geometry. Even if you’re coming off a 5-year old bike, you’ll only need a few rides to get accustomed to the Fuel EX’s steering behaviour.

Trail-tweakable

In addition to the Mino Link, we’ve also been experimenting with the lower shock flip chip on the Trek Fuel EX. Requiring just a single 6mm hex key, it’s a quick adjustment to make trailside, and the change in suspension behaviour is noticeable.

I ended up preferring the ‘Less’ setting, which provides a more linear leverage rate. With the shock set at the recommended sag, this position provides great pedalling support, along with more comfort and activity deeper into the stroke. There’s still a good deal of progression though. Combined with the large bottom-out bumper in the Float X shock, hitting full travel proved to be a well-controlled affair.

One of our fellow testers, who generally spends more time in the air than on the ground, preferred riding in the ‘More’ setting. This increases progression, providing a stronger ramp-up in the latter half of the travel. He also reduced the shock pressure by 5psi to further enhance small-bump compliance, while still being able to enjoy the additional big-hit support. Pedal efficiency isn’t as stable in this setting, but it does mean the Fuel EX takes to jumps like a duck to water, popping off lips enthusiastically and absorbing hard landings with a solid and flex-free touchdown.

One thing to note on the More/Less flip chip is that while you are altering the progression of the air spring, you’re also affecting the damper too. As well as adjusting air pressure, we found we needed to tweak the rebound and low-speed compression settings between the two positions. It is indeed a useful tuning tool, but it doesn’t dispel the need for air volume spacers entirely.

What does it struggle with?

With the Trek Fuel EX adopting a beefier frame, the added weight is noticeable compared to lighter bikes in this category. That’s compounded by the heavy-duty brakes, stocky wheels and chunky tyres, which mean there’s more inertia to overcome during micro-accelerations on an undulating climb.

For those who are looking for a sharper and sprightlier trail bike to whip through the trees along smoother singletrack, the latest Trek Top Fuel will be a better fit. In comparison, the new Fuel EX is a burlier beast that thrives on steeper and more technical terrain.

Curiously, it does feel stiffer than the electrified version, the Fuel EXe . Despite both our test bikes featuring carbon frames with a near-identical build kit, I’ve found the Fuel EX to transmit more trail feedback.

Some of this may be due to structural differences, and perhaps the more favourable sprung-to-unsprung mass ratio on the electric version thanks to the added weight of the motor and and battery. Either way, the Fuel EX doesn’t exactly exude off-camber compliance. As a lighter rider on very rocky terrain, I’ve found myself getting knocked around a little more than I would like.

This sensation reminded me of the Canyon Spectral 125 , which proved to be overly stiff and quite uncomfortable at slower riding speeds. The Fuel EX is more compliant overall than the Spectral 125, but it’s still pretty stiff.

It’s not as supple as Fuel EX models gone by

Contributing to this sensation, the suspension isn’t as plush as previous Fuel EX models, particularly those that featured the Thru Shaft shock. Those bikes did require the rider to make use of the compression lever to provide pedalling support, but it meant that in the open mode the rear end absorbed the terrain like melted butter.

You may have noticed that Trek has been making a conscious move away from proprietary suspension components lately, and that’s coincided with building bikes that offer more neutral pedalling performance. The increased anti-squat is one part of the equation on the new Fuel EX, and the other part is the custom-tuned Float X, which Trek has configured with a digressive compression tune on the main piston. This creates a decent low-speed threshold, which provides a level of support that sits between the Open and Medium settings on the previous RE:aktiv damper.

The result is that you can ride with the shock fully open, and the Fuel EX still offers great stability under pedalling inputs, with no real need to activate the climb switch. If you detest remote lockouts and having to flip shock levers all the time, this will certainly be appealing.

The downside is that the suspension isn’t as supple over smaller rubble and at slower speeds. Along with the stiff chassis and carbon wheels, more of those vibrations are transmitted to the rider. As such, careful consideration with tyre pressure is needed to maximise grip and comfort.

Because there is more support however, the Fuel EX gives your feet a stronger platform to push off of, with greater feedback during high-load scenarios. Indeed the harder and faster you push, the better the Fuel EX responds. In that sense, it’s less of a comfy cruiser like its predecessors, and more of a mid-travel bruiser that loves to ride hard and fast.

Component highs & lows

As a complete bike, the Trek Fuel EX is a solid package that puts the emphasis on capability over light weight.

The Bontrager SE5 tyres are a good example, coming in at 1,100g each on our workshop scales. They roll reasonably well given their weight and size, and we’ve found them to provide consistent grip on rocky, hard-packed soil, which will suit most Aussie trail riders. The tread is a little shallow though, and the compound isn’t the softest, which sees them struggling to latch on when the conditions are wet and loose. We’d prefer something a little stickier and toothier up front, like a Maxxis Minion DHR II with 3C MaxxGrip rubber.

While the carbon Bontrager Line Pro rims are quite stiff, they have proven to be plenty tough. We’ve tested five of these wheelsets across various bikes over the past few years and we’ve not encountered a single issue. The y also come with a two-year crash replacement guarantee, which is great insurance given the hell that you can put this bike through. Furthermore, the frame itself comes with a lifetime warranty for the original owner.

There’s still plenty of real-world protection though, including a generous two-piece armour plate that bolts to the underside of the downtube. There’s also a metal chain-suck guard behind the chainring, and a full-coverage chainstay protector. Along with the fully guided internal cable routing, the Fuel EX is an impressively quiet and rattle-free bike on the trail. Well, except for the rear thru-axle lever, which I removed after the first ride.

Otherwise the finishing details are all sound. The adoption of a bigger 34.9mm seat tube diameter is welcome, as it accommodates a stiffer and stronger dropper post, particularly for the larger sizes. Mechanics will be happy to see a threaded BB shell, and we’re fans of the downtube storage. The trap door has none of the play that we encountered on the last Fuel EX we tested, with a tight fit and a nice lever action.

It’s certainly a high quality chassis, and many riders are likely to appreciate the in-built versatility. We’re looking forward to trying out the adjustable head angle once the aftermarket cups become available, and we’d also be keen to try out the Fuel EX with a coil shock. Setting it up as a mullet will be more straightforward, especially as you only need to buy an air spring to extend the Fox 36 up to 160mm of travel.

Trek Fuel EX vs Specialized Stumpjumper

Alongside the Trek Fuel EX, the Specialized Stumpjumper is one of the most popular and well-known trail bikes in this category. In terms of travel and the overall build, the Fuel EX sits right in between the regular Stumpjumper and the Stumpjumper EVO. However, it’s the regular Stumpy that I’ve been spending the most time on lately, both in its stock configuration and with a burlier mullet setup .

Compared to the Fuel EX, the Stumpjumper has a touch less travel with a 140mm fork and 130mm at the rear. It also uses a simpler suspension layout, with the carbon models employing a flex-stay design. Combined with its slimmer tube profiles, the carbon Stumpjumper frame is very light. Specialized claims it weighs just 2.28kg including the shock, which is over a kilo lighter than a carbon Fuel EX.

This theme extends to the Stumpjumper’s build kit, with Specialized electing for the skinnier Fox 34 over the 36. Along with an in-line shock, lighter brakes, wheels and tyres, there’s a considerable difference in the overall bike weight. For example, the Stumpjumper Pro we tested weighed 12.84kg.

While the geometry is pretty similar between the two bikes, the Specialized Stumpjumper rides much lighter on the trail compared to the Trek Fuel EX. It offers more comfort, with its lithe chassis and smooth suspension performance providing better compliance over rough terrain. It’s quite sporty and sprightly, though its active suspension design does need taming on the climbs by making use of the rear shock’s compression lever.

In comparison, the Fuel EX is more naturally efficient. It’s also more planted at speed, with its sturdy chassis and supportive suspension providing better big-hit capability. It feels more like a short travel enduro bike, which will suit heavier and harder riders.

Both bikes will handle a longer fork and can be set up as a mullet, though Specialized makes a specific link for the Stumpjumper to maintain the stock geometry. There is greater versatility in the Fuel EX chassis, with the option to adjust the head angle and fit a coil shock.

As for value, the Fuel EX offers a more appealing spec package. A Stumpjumper Expert sells for $9,800 AUD and comes with a Fox 34 GRIP2 fork, SRAM G2 brakes, an X01 drivetrain, alloy wheels and handlebars. In comparison, an equivalent Fuel EX 9.8 XT sells for $800 AUD less. It gets a simpler GRIP damper for its Fox 36 fork, though it does feature a piggyback shock, a Shimano XT groupset, a carbon one-piece RSL cockpit and carbon wheels with that 2-year crash replacement guarantee.

Flow’s Verdict

For many trail riders, the Trek Fuel EX 2023 is likely to tick just about every box on your new bike wish list. It’s as up to date as it gets, featuring loads of adjustability, internal storage and a nuanced approach to its size-specific geometry. Along with the increased travel and muscly frame, it offers greater stability and big-hit control over its predecessor, while still being a fun and involving bike to ride on modern flow trails.

It is a bit of a chonker though, so those who are looking for a lightweight and speedy trail bike may be better served by the latest Top Fuel .

The stiff chassis and supportive suspension also mean the Fuel EX tends to transmit more feedback, making it less comfortable to ride over rocky terrain. We’d be curious to try out a lighter shock tune to see how much of a difference that would make to the overall ride quality, but in its stock form the Fuel EX isn’t as plush as competitors like the Giant Trance X and Specialized Stumpjumper .

It is impressively efficient though, and the stable suspension gives you a load of support when you’re really giving it the beans on the descents. In this sense, the Fuel EX is closer in feel and performance to an enduro bike. You’ll still want to look towards the Slash if you’re serious about racing, but outside of the tape the Fuel EX will handle just about everything a modern trail centre or bikepark could throw at it. And for those who really want to up the limits, the adaptable chassis can easily be configured for some pretty aggressive riding.

Indeed for those who are chasing maximum capability without going to a big, spongy enduro bike, the Fuel EX is a mighty appealing option.

You’ll still want to look towards the Slash if you’re serious about racing, but outside of the tape the Fuel EX will handle just about everything a modern trail centre or bikepark could throw at it.

Boeing's F-15EX Eagle II Soars: Ushering in a New Era for U.S. Air National Guard Airpower

Posted: June 8, 2024 | Last updated: June 8, 2024

The U.S. Air National Guard has entered a new era of defense capability with the arrival of the first operational F-15EX Eagle II, the latest and most advanced version of the renowned F-15 platform, at Portland International Airport in Oregon.

This milestone signifies a major advancement for the Air National Guard's 142nd Wing, as it transitions from its aging F-15C/D fleet to a state-of-the-art fighter aircraft tailored for homeland defense missions.

The delivery of the new F-15EX, sporting the distinct Eagle tail flash of the 142nd Wing, aligns with the U.S. Air Force's overarching strategy to recapitalize its fighter fleet.

Despite a delay of eight months, attributed to production challenges, this arrival is a testament to the collaborative efforts and problem-solving between Boeing and the U.S. Air Force.

The Air Force explained that "The process change resulted in quality deficiencies, including improperly installed tubing and wires that required time-consuming rework."

Boeing and the Air Force have since implemented corrective actions on the production line to prevent future issues.

Enhanced with Boeing’s full-size determinant assembly (FSDA) process, the new F-15EX represents a leap forward in manufacturing precision and efficiency.

Mark Sears, vice president of Boeing Fighters, acknowledged the difficulties encountered during the transition, stating, "But the complexity of the systems work relative to what we’ve done in the past was a challenge."

Sears elaborated on the adjustments made to facilitate production, "Over the last three and a half years, we’ve changed our workflow and created space for forward fuselage production, so as we move toward a rate of two a month in 2025, we’ve got the line fully streamlined."

The F-15EX Eagle II incorporates a suite of advancements that far surpass the capabilities of its predecessors.

Modern features include a robust electronic warfare suite, new radar systems, upgraded engines, and additional weapon pylons.

The aircraft's digital backbone paves the way for multi-role potential, a shift that could greatly expand the scope of missions it can undertake.

As the Air Force recalibrates its fleet, the planned acquisition has been scaled down to 98 F-15EX aircraft from an initial projection of 144.

This reduction reflects shifting budget priorities and the dynamic nature of defense planning. Nevertheless, lawmakers continue to engage in discourse over the fleet size, evidencing the strategic importance of the F-15EX in the U.S. military's arsenal.

The importance of this delivery extends beyond domestic military revitalization.

Sturdy, flex-free chassis

Superb geometry with adjustable head angle

Efficient & comfortable climbing performance

Coil shock, big fork & mullet compatibility

Mechanic-friendly frame furnishings

Internal storage

Frame is on the heavy side

Savvino-storozhevsky monastery and museum.

Zvenigorod's most famous sight is the Savvino-Storozhevsky Monastery, which was founded in 1398 by the monk Savva from the Troitse-Sergieva Lavra, at the invitation and with the support of Prince Yury Dmitrievich of Zvenigorod. Savva was later canonised as St Sabbas (Savva) of Storozhev. The monastery late flourished under the reign of Tsar Alexis, who chose the monastery as his family church and often went on pilgrimage there and made lots of donations to it. Most of the monastery’s buildings date from this time. The monastery is heavily fortified with thick walls and six towers, the most impressive of which is the Krasny Tower which also serves as the eastern entrance. The monastery was closed in 1918 and only reopened in 1995. In 1998 Patriarch Alexius II took part in a service to return the relics of St Sabbas to the monastery. Today the monastery has the status of a stauropegic monastery, which is second in status to a lavra. In addition to being a working monastery, it also holds the Zvenigorod Historical, Architectural and Art Museum.

Belfry and Neighbouring Churches

Located near the main entrance is the monastery's belfry which is perhaps the calling card of the monastery due to its uniqueness. It was built in the 1650s and the St Sergius of Radonezh’s Church was opened on the middle tier in the mid-17th century, although it was originally dedicated to the Trinity. The belfry's 35-tonne Great Bladgovestny Bell fell in 1941 and was only restored and returned in 2003. Attached to the belfry is a large refectory and the Transfiguration Church, both of which were built on the orders of Tsar Alexis in the 1650s.  

To the left of the belfry is another, smaller, refectory which is attached to the Trinity Gate-Church, which was also constructed in the 1650s on the orders of Tsar Alexis who made it his own family church. The church is elaborately decorated with colourful trims and underneath the archway is a beautiful 19th century fresco.

Nativity of Virgin Mary Cathedral

The Nativity of Virgin Mary Cathedral is the oldest building in the monastery and among the oldest buildings in the Moscow Region. It was built between 1404 and 1405 during the lifetime of St Sabbas and using the funds of Prince Yury of Zvenigorod. The white-stone cathedral is a standard four-pillar design with a single golden dome. After the death of St Sabbas he was interred in the cathedral and a new altar dedicated to him was added.

Under the reign of Tsar Alexis the cathedral was decorated with frescoes by Stepan Ryazanets, some of which remain today. Tsar Alexis also presented the cathedral with a five-tier iconostasis, the top row of icons have been preserved.

Tsaritsa's Chambers

The Nativity of Virgin Mary Cathedral is located between the Tsaritsa's Chambers of the left and the Palace of Tsar Alexis on the right. The Tsaritsa's Chambers were built in the mid-17th century for the wife of Tsar Alexey - Tsaritsa Maria Ilinichna Miloskavskaya. The design of the building is influenced by the ancient Russian architectural style. Is prettier than the Tsar's chambers opposite, being red in colour with elaborately decorated window frames and entrance.

At present the Tsaritsa's Chambers houses the Zvenigorod Historical, Architectural and Art Museum. Among its displays is an accurate recreation of the interior of a noble lady's chambers including furniture, decorations and a decorated tiled oven, and an exhibition on the history of Zvenigorod and the monastery.

Palace of Tsar Alexis

The Palace of Tsar Alexis was built in the 1650s and is now one of the best surviving examples of non-religious architecture of that era. It was built especially for Tsar Alexis who often visited the monastery on religious pilgrimages. Its most striking feature is its pretty row of nine chimney spouts which resemble towers.

Caitlin Clark and Fever beat Sky for first home win of season

• Show more sharing options
• Copy Link URL Copied!

Indiana Fever rookie Caitlin Clark tossed the ball high into the air as time expired Saturday. Veteran guard Kelsey Mitchell just started clapping.

Finally, after four consecutive home losses, the Fever were celebrating.

In the latest matchup between college rivals Clark and Angel Reese, and on a day former South Carolina star Kamilla Cardoso made her regular-season pro debut in front of another sellout crowd at Gainbridge Fieldhouse, Clark finished with 11 points, eight rebounds and six assists in a 71-70 victory over the Chicago Sky on Pride Day.

“It was great, and I think it came at a really great time,” Clark said after winning the inaugural Commissioner’s Cup game. “Our fans were awesome. They were energized. You know we really didn’t shoot the ball well at all collectively as a team and you know sometimes that’s hard for the fans, like that’s what they come to see. But I think they really appreciated our great defense tonight.”

Clark had plenty of help from her teammates. Mitchell scored 18 points, NaLyssa Smith had 17 points and nine rebounds while Kristy Wallace and Aliyah Boston each scored 10. Boston, Cardoso’s former teammate at South Carolina, also had eight rebounds as the Fever (2-8) snapped a three-game losing streak.

Dearica Hamby and Sparks can’t keep pace with Chicago Sky in loss

Marina Mabrey scores 20 points and tied a career high with six three-pointers as the Chicago Sky defeated the Sparks 83-73 for their first home win.

May 30, 2024

This contest was about much more than scores or stats, though.

It featured three of the top seven picks from this year’s draft — three players in a generational rookie class who could all become the new faces of the WNBA — and a week in which Fever fans were treated to seeing each of the top four draft picks and five of the top seven.

This time, Clark got the upper hand on two of the women who prevented her from winning an NCAA championship even as she took a shoulder shot from Chennedy Carter before an inbound pass during the third quarter. The refs called it an away-from-the-ball foul.

Carter said she wouldn’t take any questions about Clark.

“I wasn’t expecting it,” Clark said initially. “It is what it is. It’s a physical game. Go make the free throw and execute on offense, and I feel like that’s kind of what we did.”

The rematches between Clark, a two-time NCAA player of the year and two-time Division I runner-up, against Cardoso, who won her second title with the Gamecocks in March, and especially Reese, who led LSU to the 2023 national title, captivated the crowd.

Before the game, Fever coach Christie Sides attempted to play up the rivalry between the two Midwestern teams, but the loud pregame ovation for Clark and a smattering of boos that were quickly drowned out by cheers for Reese during pregame introductions typified the showdown.

Reese finished with eight points and 13 rebounds in her latest round against Clark and did not take questions from reporters following the game. Cardoso played for the first time since injuring her right shoulder in a preseason game May 3 and had 11 points and six rebounds in 18 minutes but was called for a foul that led to Boston’s three-point play with 1:19 left, which proved the difference. Chicago’s Marina Mabrey missed a free throw with 6.6 seconds left to seal it.

“First game back and she played pretty well, too,” said Carter, who had 19 points and six assists to lead the Sky (3-4). “She hasn’t been in this position, closing the game, so let’s give her some time.”

Mabrey finished with 15 points and nine rebounds for Chicago.

Cardoso entered for the first time midway through the first quarter and wasted no time making an impact. She had six points and four rebounds during a six-minute stint in which the Sky erased a 22-16 deficit, took the lead and sustained the momentum to complete a 15-4 spurt after Cardoso departed midway through the second quarter.

Clark helped ignite Indiana’s response, a 9-0 run just before halftime, to give the Fever a 35-31 lead.

Chicago charged back to tie the score at 37 early in the second half, but Indiana answered with six straight points and closed the third quarter with a 54-49 lead. The Sky rallied again late after falling into a 68-58 deficit and closed the game on a 12-3 run — but couldn’t quite come all the way back.

“I thought earlier this season if we would have shot like this, we wouldn’t have won the game because we didn’t have that resiliency and we would have let it affect our defensive play,” Clark said. “So just proud of us, I thought we were really gritty.”
