Plus, powerful Shimano XT 4-piston hydraulic disc brakes, Tubeless Ready Bontrager Line Carbon 30 wheels with a 54-tooth Rapid Drive rear hub for quick engagement, and a Bontrager Line Pro OCLV Carbon handlebar. An internal storage compartment lets you securely stow ride essentials and doesn't detract from the bike's sleek look.

"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."

"Good at pleasing everybody"

"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 at it."

"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."

Features

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.

Mino Link adjustable geometry

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.

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 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.
