Background and Identification
The A310 Hard Tail Mountain Bike features an aluminum frame, which is both sturdy and lightweight. It's built to allow you to sit a little bit more upright, making for a much more comfortable ride and is equipped with an SR Suntour fork with 80mm of travel to handle rough terrain. For brakes, this bike sports a set of Avid BB5 mechanical disc brakes, which help as you travel down the mountain. Other specs include Sram X4 shifters and a rear derailleur.
