The 1988 GT Pro Performer. If your plans include making waves as big as Martin Aparijo's, why not give yourself a headstart on the GT Pro Performer. Like our more sophisticated styler, the Pro Performer is made in the USA by people who know freestyle. A Gyro keeps things spinning and GT Performer Mags roll over any punishment suburban streets can deliver. From neighborhood driveways to the Masters Series final, nothing beats the GT Pro Performer.
