Trek Fuel EX 8 XT Trail Bike in Nautical Navy

Season:2025

Brand:Trek

Code:41327BLU

The Fuel EX 8 XT is an evolved trail bike, dialled 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

Features:

  • 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
