Overview

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.
