Overview
About this bike
GT's Performer is pretty much the bike that introduced freestyle to the world almost 30 years ago. This pint-sized version promises to take your grom's skills to a new level, just like the original did a whole generation ago. The 18-inch wheels are a great transitional size, letting young riders progress their way to a full-sized ride down the road. Boasting a steel frame and stout aluminum wheels, the Performer is ready to carry out the craziest of tricks. And it comes with class-defining BMX specs like 3-piece tubular-chromoly cranks, 25/9 micro gearing with a 1-piece driver, and plastic pedals. The torch has been passed.
