'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.'

'Good at pleasing everybody.'
'The Fuel EX has a few tricks that help it keep a level head when outside of its comfort zone, and to be a cloud on rails when it's in the zone. Everything about the Fuel EX, which was already good at pleasing everybody, is now even better.'

'An absolute trail rocket.'
'Thanks to its burlier components, increased travel and more aggressive geometry, it has become more of a shredder than ever! More performance, fun and trail prowess.'

‘Perfect all-rounder’

See the bikesWill 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.
Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
RE:aktiv technology gives you firm support for efficient pedaling that instantly gives way for smooth control when the trail turns rough.
Trek's Straight Shot frame design optimises the stiffness-to-weight ratio for a more responsive ride. You'll be able to push harder and stay more planted on your line when the going gets rough.

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.
Boost148/110
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.
