2018 GT Grunge 20
2018 GT Grunge 20 is a single-speed kids bike featuring an alloy LegitFit frame, one-piece 32T crankset, and coaster brake for young riders.
Description
Sure, we had grunge in the 90's, but it was never this much fun. Channel your little rocker's energy into two wheels and get them gunning for a different kind of stage from an early age with a single-speed bike built just for riders who are growing up through the ranks. The LegitFit system gives them better positioning, easier pedaling, and a faster start to your next ride.
