The Fuel EX 8 GX AXS 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 a upgraded electronic wireless 12-speed SRAM GX Eagle transmission, while a 150 mm FOX Rhythm fork 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 tubeless hoops.
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. SRAM's latest wireless GX Eagle AXS 12-speed transmission 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.
