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 balances efficiency with shred-ability. 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, 120mm RockShox SID fork with plush DebonAir spring, 120mm of rear travel with a FOX Performance Float 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.
