Overview
About this bike
GT's Avalanche Sport is great for all types of riding, from exploring singletrack to running errands around town. It boasts GT's light, stiff 6061-aluminum frame for easy pedaling and a 100mm-travel SR Suntour suspension fork to smooth out bumps for total control. You also get easy-rolling, 27.5-inch aluminum wheels with versatile Continental tires, a slick-shifting 27-speed Shimano drivetrain so you can cruise over hills, and Tektro hydraulic disc brakes for the flight back down.
