Details

Top Fuel 8 fuses the speed of a cross country bike with the capability and forgiveness of a full suspension trail bike. It's quick, nimble, and dishes out serious fun on flow trails and techy descents alike.

IT'S RIGHT FOR YOU IF…
You're looking for a do-it-all full suspension mountain bike that is efficient yet can get rowdy. You want to rip rough descents, fly up climbs, and crush lap after lap.

THE TECH YOU GET
A lightweight aluminum frame with internal storage, 130mm RockShox Pike fork with plush DebonAir spring, 120mm of rear travel with a RockShox Deluxe Ultimate RCT shock, and a Shimano XT drivetrain. Plus, 4-piston brakes for confident descents, Bontrager Line Comp 30 wheels that are already completely tubeless ready, including sealant, and a Bontrager Line Dropper.

THE FINAL WORD
Top Fuel 8 gets you the value of an alloy frame with drivetrain, fork, and brake upgrades that keep up as you progress in speed and skill.

WHY YOU'LL LOVE IT
- This bike's killer suspension setup is both efficient and ready to party
- You get wide Bontrager Line Comp 30 wheels that boost grip and reduce flats with their tubeless setup
- 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
