It's right for you if...
You want a single carbon trail bike that can take on every adventure, from singletrack to the gnarliest descents and multi-stage endurance events. You prioritise a lightweight frame and performance suspension over the highest-end drive train available.
The tech you get
A lightweight and stiff full OCLV Mountain Carbon frame with Carbon Armour, a 140 mm FOX Rhythm 34 fork, 130 mm 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 drive train, 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!'
'The 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 pedalling, 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.
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 set-up.
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 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
