Fuel EX 8 GX AXS 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 a upgraded electronic wireless 12-speed SRAM GX Eagle transmission, while a 150mm 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.
Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
Install angle adjust headset cups (sold separately) to tweak the 64.5-degree head tube angle a degree steeper or slacker to your liking — all without impacting your bottom bracket height.
Adjust leverage rate with just a flip of a chip. Ride it in the Less progressive setting for a plusher feel perfect for rugged trails with square-edge bumps. Flip it to More progressive when you're hitting big features and don’t want to bottom-out, or when you want to run a coil shock.
Size-specific chainstays provide balanced handling to keep the ride nimble for smaller riders and improve front wheel traction on climbs for taller riders.
Craving the nimble ride of 27.5˝ wheels but don’t want to sacrifice the speed of a 29er? No need to choose. Fuel EX is mullet-ready, just throw Mino Link in high, toss on a160mm fork, and get ready to party.
