  • RE:aktiv: All-new mountai...


Shred singletrack like there's no tomorrow with Trek's unstoppable Fuel EX 9.8 29. The OCLV Carbon frame uses Trek's super-efficient Full Floater and ABP rear suspension tech that makes every ride better, faster, and simply more fun. Stiffness means efficiency and better handling, so you're armed with an E2 head tube and wheel-enhancing Boost hub spacing. Fox handles the suspension with a 120mm Performance 34 Float and a RE:aktiv Float shock, both of which absolutely crush the ups and downs on every trail. Rounding out the build is Shimano's unflappable 2x11 XT group, a Reverb Stealth dropper post, Bontrager carbon bars, and DT Swiss tubeless-ready wheels wrapped with fat rubber. There's no tomorrow, so get out there and shred.

Features & Info

Trek’s Full Floater Shock Mount

Trek's Full Floater shock mount boasts two suspended points that allow the shock to "float" through its range of action for seemingly bottomless travel and excellent tracking over every type of terrain.

Stealth Cable Routing

For a clean dropper post setup, Trek uses RockShox’s Reverb Stealth dropper seatpost and internal frame routing. The housing runs inside the frame for a clean look and zero hose issues as the saddle moves up and down.

E2 Head Tube

Trek's E2 head tube is 1.5-inches in diameter at the bottom and 1 1/8-inches at the top. This maximizes front-end stiffness for awesome steering precision and control, while allowing the use of standard 1 1/8-inch stems and not adding much weight.

EVO Rocker Link

Trek's EVO rocker link is a one-piece, magnesium linkage that drastically increases rear-end stiffness and decreases total frame weight, too.

G2 geometry

Trek's G2 Geometry (version 2 of Gary Fisher's Genesis Geometry) delivers the ultimate ride for every trail. Genesis earned rave reviews for awesome handling on climbs and descents thanks to a long top tube paired with a short stem that moves the front wheel forward for top-notch confidence and control, while short chainstays add phenomenal traction. G2 Geometry takes these handling traits to the next level by boosting control on tight singletrack and technical climbs, too. This is accomplished by increasing the amount of fork offset (reducing trail), which makes G2 bikes steer more quickly, and by shortening the reach, which puts more weight on the front wheel for even better control and confidence. The two animations above showcase how G2 Geometry provides the perfect ride.

Stiff like a race bike, yet floats thru the rough stuff

I ride all the trails in the area and harder ones in more exotic locations like Moab and Whistler, and here is final a bike that can go darn nearly as fast as the latest race bikes (faster than my several year old XC race bike actually could) and yet can easily tackle much harder terrain than any of those could go near. I love it. It needs the tubeless conversion done, but not much else!

Couldn't justify 9.9 Fuel Project One, but didn't loose anything but some gold on the fork and shock, the paint custom and used the saving to get a set of carbon wheel and lighter tires and factory upgrade to Sram X01. Thanks Trek for the 9.8 Fuel I have my dream bike.
