Trek Fuel EX 8 XT (Gen 6) Full Suspension Bike 2025
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 150mm 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 150mm 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 setup.
The final word
For the rider who doesn't want to be limited on the trail, 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
- Fuel EX Gen 6 gives you 140/150mm of travel and slack, adjustable geometry for an extra capable ride, plus, in-frame storage on all models — even alloy
- 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
