Overview
About this bike
Whether you're looking to add some new trophies to your shelf, or just blast local trails with your riding buddies, GT's Helion Carbon Pro sports the acceleration and handling required to ensure every day on the trail is a winner. GT's light and nimble carbon frame soaks up trail obstacles with Fox-powered front and rear suspension, while GT's XC-oriented geometry places s heavy emphasis on speed, efficiency, and agility. The whole thing rolls on Stan's tubeless-ready Crest rims, 350 hubs from DT Swiss and grippy 27.5-inch Continental tires that keep you pinned in the corners. Meanwhile, a light and fast 1x10 Shimano XT drivetrain graces the Helion Carbon Pro, with a Race Face Turbine crankset to transfer your torque to the trails. And, powerful Shimano XT hydraulic discs mean you can brake later and corner faster, all with impeccable control. The rest of the Pro is equally high-tech with Race Face's Turbine bar, stem, and seatpost, and a Fizik Tundra saddle.
