- Alpha Platinum Aluminum is lightweight and trail-tough
- Efficient and capable: you can build up this frameset to suit a wide range of trails and terrain
- Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius
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
120mm 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.
Will my bike have a curved top tube?
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. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically dont have the same issues with standover height.
