Description
The 2009 GT Stomper 20 is a youth mountain bike built around GT’s Triple Triangle 6061 aluminum hardtail frame, sized for riders ready to move beyond balance bikes and entry-level cycling. The SR M2000 fork provides 75 mm of travel up front, giving young riders a degree of trail compliance, while 24 x 1.95 Kenda ATB dual-purpose tires on aluminum rims handle mixed surfaces comfortably.
Drivetrain duties fall to a single 36-tooth aluminum crankset paired with a Shimano TX-30 rear derailleur and SRAM MRX 7-speed shifters — a straightforward setup that keeps shifting intuitive for developing riders. Tektro linear-pull brakes round out a spec sheet focused on durability and ease of use.
