A couple months ago, I was on the hunt for a new mid-travel personal bike and found myself largely unconvinced by most of the offerings on the market. Then a new, highly adjustable and longer in the tooth Trek Fuel EX was announced. When I reached out to Trek to inquire about testing one they offered to send a frameset for me to build out. On paper given that it had my ideal geometry, loads of adjustments (including leverage rate!), internal storage and the options of  air or coil and mullet or straight 29″, this was the ultimate Swiss army

The downtube storage compartment is on the new bike, and while it seems like Trek has put all the things onto the latest Fuel EX, there's one that they didn't: Knock Block.

Wide range of effective geometry adjustments

Just as much fun on smooth trails as it is on scary trails

Great climber, efficient pedaling

One-piece handlebar might be too stiff for some riders

Paint chips easily

New geometry, more travel, and even better suspension improves Trek's mid-weight trail bike.

Trek’s alloy Fuel EX trail mountain bike lacks the latest features but is the overall package still a winner?

Tight, precise frame

Sorted all round handling

Very efficient suspension feel

Durable Shimano kit

Excellent sizing options

Heavy frame

No internal storage

Press fit bottom bracket

Top Fuel is more playful

The Trek Fuel EX has proven itself as an excellent all-rounder in the past. This year, the American brand enters the race with the € 5,999 Trek Fuel EX 9.8 GX, which combines a high-end frame with a mid-level spec but still features Trek's Thru Shaft shock technology. So does it always have to be top-spec? How big is the difference in performance and how does the Fuel EX 9.8 GX fare against its more expensive peers?

Very comfortable uphill

Intuitive handling

High-quality frame with integrated storage compartment

Tires are very puncture prone and generate little traction

Brakes don't do the bike’s potential justice

The Trek Fuel EX 9.9 is an absolute classic in the trail bike segment. Could it also be the perfect bike for the next bikepacking adventure with its modern geometry and spare parts compartment in the down tube? We put the Fuel EX to the test.

Maximum fun on the descents

Intuitive and good-natured handling

Storage compartment in the down tube for tools or snacks

Too sluggish on easy terrain

Too much bike for long straights

Jun 2020 · Spencer Johnson

As warmer temperatures hit the Pacific Northwest and the dirt starts to dry, I’m always eager to get out on some long rides with some big climbs. Naturally, when this Trek Fuel EX 9.9 showed up at the Freehub office, I knew it was time to put the nimble beast through its paces. I challenged myself to a 60-mile sufferfest on some of Bellingham, Washington’s toughest climbs and descents. It definitely didn’t let me down. Climbing on this bike was a joy. Trek equipped the 9.9 model with its proprietary RE:aktiv shock with a three-position damper, which I left wide open for the entire ride. The rear suspension had an overwhelmingly supportive feel while pedaling out of the saddle, yet as soon as I hit a bump it dived deeper into the travel, keeping the rear wheel firmly planted and providing excellent traction. The geometry is modern and balanced, with a long reach and a sensible 76-degree seat angle. On the descents, the bike inspired confidence, thanks to its long wheelbase and bottomless-feeling suspension. My confidence was further enhanced by the reliable stopping power of the Shimano XT brakes. As a 200-pound rider, I couldn’t have appreciated the ultra-powerful XT brakes and the 203-millimeter front rotor more—especially while bombing down some of Bellingham’s scariest double-black trails.

  Who’s it for?

  The updated Gen 6 model is for riders who love all trails, flowy, rocky, steep, loose, and otherwise. It's for the renaissance rider who rides it all.

  The adjustable geometry and suspension flip chip appeal to mountain bikers who prioritize tuning their setup to the current conditions. 

  The Fuel EX is the longer-travel sibling of the snappy Trek Top Fuel designed for lighter, more XC style trails.

  

  Why you'll love it

  The Fuel EX is in a league of its own when it comes to on-the-go adjustability. 

  Riders can now easily customize their geometry and suspension progression at the flip of a chip and optimize their ride no matter the trail. 

  You’ll enjoy full days of downhill shuttle runs more than ever thanks to the redesigned frame, downtube guard, and handy internal storage.

  What's new on the 2023 Trek Fuel EX?

  Check out the Trek Fuel EX overview below and learn about all its exciting updates.

  

  More front and rear travel

  Year after year, riders continue to push the limits of trail bikes and the Fuel EX Gen 6 delivers longer travel suspension for dominating steeper terrain. 

  Front travel increases from 130mm to 140mm and the rear shock provides 150mm of cushion, up from 140mm on the previous model.

  

  Adjustable Geometry

  The 2023 Fuel EX also introduces an innovative adjustable headset that can alter the head tube angle by +/- 1 degree depending on the desired slackness. 

  The head tube angle can be set between 63.5 and 65.5 degrees. 

  The angle adjust cups combine with the Mino Link for a total of 6 possible geometry configurations.

  

  Size specific builds

  Trek has matched the frame sizes with appropriate wheel choices and chainstay lengths to ensure all riders achieve an ideal fit. 

  XS models run nimble 27.5” wheels whereas frame sizes medium and up have 29ers. Small frames are available in both wheel options. 

  All riders, regardless of their height, can find a bike that provides maximum control and handling.

  

  New frame features

  The reimagined frame boasts trendy tech, including a full length downtube guard for protection from debris and tailgates during shuttle runs. 

  The new threaded BB and guided internal routing keep everything neatly tucked away and low-maintenance. 

  The larger 34.6mm seat tube accommodates sturdier dropper posts and now all frames— carbon and alloy— come with handy downtube storage .

  

  Adjustable suspension progression

  Riders can effortlessly switch between suspension settings via a flip chip on the lower shock mount. 

  Choose between the plush, less progressive setting for better trail feedback or the more progressive setting that’s better for aggressive riding. 

  The progressive option avoids bottoming-out and performs great with linear coil shocks if you choose to upgrade later on.

  Trek Fuel EX Geometry

  The new Fuel EX features a steeper seat angle and longer reach for more efficient climbing and improved handling on demanding descents. 

  This more aggressive geometry can be further fine-tuned from inside the headset with angle adjust cups (sold separately) as well as the rear triangle Mino Link, r esulting in 6 different geo configurations .

  Trek Fuel EX Size Chart

  Trek outfitted each frame option with the correct wheel size to optimize handling. XS models come with 27.5” wheels, frames M and up run 29ers. People who ride S frames are often caught in the middle, so those frames are available with both wheel options.

  *Size XXL available in alloy only.
