Trek Fuel EX 8 Gen 7 MTB

Jack of all trails

Flow, tech or steeps – the Fuel is up to get down. This trail ripper features ultra-adjustable geometry that lets you choose your own adventure, whether you’re after a stoic trail tamer, rowdy MX ride or enduro-ready beast. Three build options and endless tweaks mean you can get a ride that’s fine-tuned for your style and stomping grounds. Wherever the trail leads you, the Fuel is ready to send.

The Fuel EX 8 is a confident and versatile trail bike built to get after it. It comes ready to rip with an Alpha NEXT Platinum frame, Fox performance suspension package with 145 mm/150 mm travel (rear, front), alloy Bontrager Line wheels and a SRAM Eagle 70 transmission that keeps shifts smooth, even under load. It's topped off with 4-piston SRAM DB 8 hydraulic disc brakes to keep you stopping on a penny.

Adapt, rip, repeat

Only you can define your perfect trail bike – that's why Fuel is available in three adjustability-packed configurations. Get do-it-all capability with EX, go pop-happy with MX or charge through it all with LX.

Adjustable leverage rate

Want more bottom-out resistance without giving up small-bump sensitivity? Flip the chip in the lower shock mount for a more progressive leverage rate.

Zero stack integrated headset

With a ZS standard headset, you've got loads of options for aftermarket upgrades, including angle adjust or anodised colours.

Storage and accessory mounts

Stash ride essentials with in-frame storage on all Fuel models – both carbon and alloy. Plus, top tube accessory mounts let you load up even more.

Fresh frame design

The Fuel's new frame gives you loads of room for long dropper posts, bigger shocks, frame bags and more.

Active Braking Pivot

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.

Transition to transmission

The SRAM Eagle T-Type transmission mounts directly to the frame, skipping that pesky derailleur hanger of yesteryear. This makes for a more robust system that's not only cleaner-looking, it's also more precise under load and easier to set up.
