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. Plus, you get the upgrade of wireless electronic shifting.

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 SRAM GX Eagle AXS wireless 12-speed transmission. Plus, 4-piston brakes for confident descents, Bontrager Line Comp 30 wheels that are already set up tubeless, 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 clean shifts, even under load, with SRAM's smart, smooth, and completely wireless GX Eagle AXS transmission
- 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
