Overview
About this bike
Wherever you love to ride, GT's Helion Comp is ready! XC frames are all about fast-riding fun and jaw-dropping agility. So, the Comp emphasizes speed and handling, paired with 110mm of Raidon front-end suspension and a 130mm X-Fusion rear shock. With a pair of 27.5-inch GT All Terra hoops wrapped with WTB's Beeline tires to lead the way, you're in charge, no matter what the trail ahead may hold. Plus, the Shimano 3x9 drivetrain has the gears to power up every climb, and the fast, smooth performance to hit every shift, while their hydraulic-disc brakes mean all-weather stopping power for total control. And, the rest of this rig is dressed to the nines with GT's own bar, stem, post and seat.
