Top Fuel 8

Model 584314

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.
