  • Adapt, rip, repeat

    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

    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

    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

    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

    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

    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

    Transition to transmission

    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.

Overview

Fuel EX 9.9 X0 AXS is our cream-of-the-crop versatile trail bike, built for taking on any trail, any time. Its OCLV Mountain Carbon frame partners with a RockShox Deluxe Ultimate shock and Lyrik Ultimate fork (145mm, 150mm) to give you the travel you need for rowdy roots and jump lines. For smooth shifts, it's speced with a wireless X0 Eagle AXS transmission, while SRAM Maven Silver 4-piston brakes keep you stopping on a dime. It's finished off with OCLV Mountain Carbon Bontrager Line Pro 30 wheels and an upgraded RockShox Reverb AXS wireless dropper post.
