Overview
About this bike
Whether you're looking to add some new trophies to your shelf or blast local trails with your riding buddies, GT's Helion Carbon Expert 9R 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 heavy emphasis on speed, efficiency, and agility. The whole thing rolls on WTB's STS i23 rims and grippy, 29" Schwalbe Racing Ralph Snakeskin tires that keep you pinned in the corners. Meanwhile, a light and fast 2 x 11-speed Shimano drivetrain graces the Helion Carbon Expert 9R, with a Race Face Ride crankset to transfer your torque to the trails. And, powerful Shimano SLX hydraulic discs mean you can brake later and corner faster, all with impeccable control. The rest of the setup is equally high-tech with a Race Face Ride bar, stem, and seatpost, and a WTB Silverado Race SL saddle.
