Internal Storage

Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.





Active Braking Pivot

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.





Slack or steep, the choice is yours

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 the sus for full send

Adjust the 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 stays

Size-specific chainstays provide balanced handling to keep the ride nimble for smaller riders and improve front wheel traction on climbs for taller riders.



Business at the front, party at the back

Craving the nimble ride of 27.5? wheels but don?t want to sacrifice the speed of a 29er? No need to choose. The Fuel EX is mullet-ready, just throw Mino Link into high, toss on a 160 mm fork and get ready to party.
