Trek's 3500 is a quality mountain bike ready for every adventure. Trek's White Series aluminum frame is light for nimble handling, easy acceleration and climbing. It's also built tough so it's fully capable of handing serious trail riding for a lifetime of fun. Plus, the 3500's 63mm-travel suspension fork dispatches bumps, rough trails, rocks and roots with ease and grace. This trail-tamer delivers in the components department too, with a quick-shifting 21-speed Shimano drivetrain that makes easy work of the hills, powerful Tektro linear-pull brakes and a nice set of Bontrager wheels.
