Overview
About this bike
Whether you want more fun on your local singletrack or unexplored trails are calling your name, GT's Helion Carbon Expert is ready to go. Its GT carbon frame is light and nimble and it soaks up trail obstacles with plush, controllable suspension powered by a RockShox Reba RL fork and a Fox Float rear shock, while GT's XC-oriented geometry places heavy emphasis on speed, efficiency and agility. The Expert rolls on Stan's tubeless-ready Rapid rims, quality Shimano SLX hubs, and grippy Continental 27.5-inch tires that keep you pinned in the corners. A 2x10 Shimano SLX/XT drivetrain keeps things competitive, with the go-fast gears to distance your crew and the climbing capability to tackle epic days in the saddle. You also get powerful Shimano SLX discs so you can brake later and corner faster, all with impeccable control. The rest of this ready rig is dressed to the nines with Race Face's Ride bar, stem, and seatpost, and a fine Fizik Tundra saddle.
