Top Fuel 5 is a full suspension mountain bike that’s equal parts efficient and capable. It soaks up rough, rugged descents but still flies like a rocket up hills and on flat stretches. The light and sturdy alloy frame is built with parts picked for performance and value, making this bike perfect for your first full suspension trail bike.
  • This bike’s killer suspension setup is both efficient and ready to party
  • 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.

Shimano Deore

Shimano Deore brings even more adventure with a wider range of gear choices for the steep stuff, the fast stuff, and the fun. With smooth riding, improved chain stability, and sharp shifting, Deore heightens your mountain biking confidence and control so you can focus on the trail and enjoy the ride.
