Fuel LX 9.8 Eagle 90 is a rowdy carbon trail bike ready to slay steep descents and blast through wheel-gobbling terrain. Its OCLV Mountain Carbon frame partners with a RockShox ZEB Ultimate fork and Vivid Ultimate shock (160mm rear, 170mm front) for going all-out on the wildest lines on the mountain. A mechanical SRAM Eagle 90 transmission gives you reliable shifts without the fuss of electronics, and 4-piston SRAM Maven Bronze brakes deliver power you can count on.

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 tons of options for aftermarket upgrades, including angle adjust or anodized colors.

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

Fuel's new frame gives you tons 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.
