Overview
About this bike
Light, lively and sure to leave a grin plastered across your face, GT's Helion Expert is the key to trail-riding bliss. The light GT aluminum frame soaks up trail obstacles with 110mm of plush, controllable front-end suspension powered by a Fox Float fork, plus their 130mm rear shock, while GT's XC-oriented geometry places heavy emphasis on speed, efficiency and agility. This capable machine rolls on WTB UST-tubeless wheels, quality Shimano SLX hubs, and grippy Continental 27.5-inch tires to keep you pinned in the corners. Meanwhile, the 2x10 Shimano Deore/SLX drivetrain keeps things fast, with the precision shifting it takes to drop your buddies and the climbing capability to tackle epic days in the saddle. Plus, the Shimano Deore hydraulic discs provide awesome speed control for setting personal bests on local descents. And, the rest of the Expert is dressed to the nines with Race Face's Ride bar, stem, and seatpost, and a choice WTB saddle.
