Color: Satin Trek Black
Satin Trek Black

Top Fuel 8 fuses the lightweight efficiency of a cross country bike with the capability and forgiveness of a full suspension trail bike. It's quick and 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 even do a couple XC races.

The tech you get

A lightweight aluminium frame, 120 mm RockShox Recon Gold RL fork with plush DebonAir spring, 115 mm of rear travel with a FOX Performance Float shock and a lighter SRAM NX Eagle drive train. Plus, hydraulic disc brakes, Bontrager DropLock dual remote suspension lockout and a Bontrager Line Dropper.

The final word

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