2021 Trek Top Fuel 8 NX
Regular price
$4,899.00
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, 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 aluminum frame, 120mm RockShox Recon Gold RL fork with plush DebonAir spring, 115mm of rear travel with a FOX Performance Float shock, and a lighter SRAM NX Eagle drivetrain. 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 drivetrain, fork, and brake upgrades that keep up as you progress in speed and skill.
