2021 GT Stomper Prime 20

Small wheels doesn’t mean small fun: this is GT’s premium off-road, all-terrain, all-action first mountain bike. Lightweight aluminum frame and rigid fork built with LegitFit design and plenty of Shimano gears mean this bike is super-easy to ride and handles like a dream. Remember that feeling of barrelling down the dirt track and coming home covered in mud while grinning from ear to ear? THAT!
