Internal Storage

Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.

Active Braking Pivot

Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently meaning you get more confident control when you need it most.

Size-specific stays

Size-specific chain stays provide balanced handling to keep the ride nimble for smaller riders and improve front wheel traction on climbs for taller riders.

Simano XT

Reliable shifting. Superior braking. Intuitive maintenance. XT is the high performance workhorse you can count on.


The Fuel EX 8 XT is an evolved trail bike, dialed for riders who chase down rowdy descents and want a bike that's happy to pedal back to the top and do it again.

The lightweight alloy frame pairs with upgraded 12-speed Shimano XT drivetrain to keep shifting precise while a 150 mm FOX Rhythm fork with Float EVOL air spring cushions the blow from rocks and roots. In-frame storage and adjustable geometry give you all the perks that the come with the carbon model, but without the lofty price tag.

It's right for you if...

You want a full-suspension trail bike that floats over rough and technical terrain, and packs in plusses, like a root-slaying FOX Rhythm fork and Shimano's clean-shifting 12-speed XT drivetrain.

The tech you get

A light and stiff alloy frame with 150 mm FOX Rhythm fork with Float EVOL air spring and GRIP damper for small bump compliance, plus a FOX Performance Float X rear shock. A Shimano XT 12-speed drivetrain for snappy shifting and Tubeless-Ready Bontrager wheels. Plus, adjustable geometry that lets you take control of your set-up.

The final word

For the rider who doesn't want to be limited on the trail, the Fuel EX 8 is ready to handle everything. Its progressive trail geometry is built to keep you charging, and upgraded components are the cherry on top.

Why you'll love it

  • The Fuel EX Gen 6 gives you 140/150 mm of travel with extra adjustability features and more stable handling, plus a more robust frame with internal storage
  • You'll get upgraded components where it matters most, with 12-speed XT shifting and a rock-gobbling FOX Rhythm 36 fork
  • With the adjustable angle headset (angled cups sold separately) and Mino Link, you can choose from six different geometry configurations
  • The dropper post lets you lower your saddle on the fly so it's out of the way on descents
  • We expanded our size range to ensure a better fit for all riders, and use the best-fitting wheels for each frame size: XS frames get 27.5˝ wheels, S frames get to choose between 27.5˝ or 29˝, and sizes M and up get 29˝ wheels
****NOTE: This bike is available for purchase online, but must be picked up from an approved store.
