The tech you get
A lightweight and stiff full OCLV Mountain Carbon frame with Carbon Armor, a 140mm FOX Rhythm 34 fork, 130mm of rear travel with a FOX Float Performance rear shock with Trek's exclusive RE:aktiv damper, a wide-range 1x12 SRAM NX/GX Eagle drivetrain, a Bontrager Line dropper post, Tubeless Ready Bontrager Line Comp 30 wheels, and powerful Shimano 4-piston hydraulic disc brakes. An internal storage compartment and Control Freak cable routing add to the bike's capability and sleek look.
The final word
Fuel EX full suspension performance on a lightweight and trail-tough carbon frame makes for a fun and fast ride. This rugged, capable bike sails down descents and helps you hang tough during fatiguing marathon rides.

"A world-class trail bike"
"Fuel EX is a beautifully balanced and capable trail bike. The rear suspension is beautiful; as close to ideal as any bike I've ridden. It's sensitive where you want it to be, firm and crisp where it should be. It feels deep and controls big hits very well, and there's a nice platform for pedaling, and to pump and pop off when you're playing."Read more

Will my bike have a curved top tube?
Smaller frames (XS and S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
Complete Tubeless System
Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. You're ready to roll right out of the box with the included TLR rim strips, valves, and sealant.
Control Freak Cable Management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout, and dropper post lines to be routed through the frame for clean looks and the ultimate custom setup.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
