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.

Quick and in control
120 mm of rear travel combined with progressive trail geometry gives you a fast, responsive ride that helps you keep your cool when the trail turns rowdy.

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

Hassle-free routing
Guided internal cable routing keeps Top Fuel quiet on the trail and maintenance a breeze.

BITS: Your trail-side saviour
Cleverly integrated into the steerer tube, the included BITS multi-tool has everything you need for trail-side adjustments and repairs.

Will my bike have a curved top tube?
The smaller frames (XS and S) have a curved top tube. This design makes for a lower standover height, which allows shorter riders to straddle the bike more easily. The larger frames (M and up) have a straight top tube because taller riders with longer legs typically don't have the same issues with standover height.
