The Fuel EX 8 is a dialled trail bike for riders who chase down rowdy descents and want a bike that's happy to pedal back to the top and do it again. It has a stout alloy frame and an upgraded Shimano XT drivetrain for smooth precise shifting. The 150 mm Fox Rhythm fork makes easy work of rocks and roots while the Fox Float X shock keeps you in control. New in-frame storage and adjustable geometry give you all the perks that come with the carbon model, but without the lofty price tag.
You want a full-suspension trail bike that prioritises suspension and shifting performance over a more expensive carbon frame.
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, new adjustable geometry that lets you take control of your set-up.
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 they cherry on top.
