Top Fuel 8 fuses the lightweight efficiency of a cross country bike with the capability and forgiveness of a trail bike. It's quick, nimble, and dishes out serious fun on flow trails and techy descents alike, with a 120mm RockShox fork, 115mm of rear travel, and a dropper post for getting low on the rough stuff. This bike is fully capable of shredding singletrack, racing grueling endurance events, and even holds its own on the XC course.
It's right for you if...
You’re looking for a do-it-all full suspension mountain bike that balances efficiency with capability. You want to rip rough trails, do a couple XC races, and even test yourself with an endurance or stage race.
The tech you get
A lightweight Alpha Platinum Aluminum frame, 120mm RockShox Recon RL fork with Motion Control damper, 115mm of rear travel with a Fox Performance Float shock, and a 1x12 SRAM NX Eagle drivetrain.

The final word
Top Fuel 8 is an efficient, capable, and ridiculously fun short-travel full suspension trail bike. It's built to take on technical terrain, flowy XC courses, and the demands of endurance mountain bike races.
