Overview
About this bike
Light, lively, and sure to leave a grin plastered across your face, GT's Helion Expert 9R is the key to trail-riding bliss. The light GT aluminum frame soaks up trail obstacles with 100mm of plush, controllable front-end suspension powered by a Fox Performance 32 Float fork and a Fox Performance Elite Float Air Shock in back. This capable machine rolls on WTB ST 29-inch wheels, quality Shimano SLX hubs, and grippy Schwalbe Racing Ralph Snakeskin tires to keep you pinned in the corners. Meanwhile, the 2 x 11-speed Shimano SLX drivetrain keeps things fast—with the precision shifting it takes to drop your buddies. Plus, the Shimano Deore hydraulic discs provide awesome speed control for setting personal bests on local descents. And, the rest of the Expert is decked out with a Race Face seatpost and a choice WTB saddle.
