Overview
About this bike
GT's Timberline Comp conquers singletrack, trips downtown, and daily commutes with a nimble, light, and stiff 6061-aluminum Triple-Triangle frame. Up front, an SR Suntour suspension fork tames all the bumps. And for the go, a quick-shifting 24-speed Shimano drivetrain provides the tools necessary to tackle rolling terrain on and off road. The big 29-inch wheels let you steamroll obstacles, while the grippy GT All-Terrain tires provide control and confidence. Go everywhere on the Timberline Comp!
