The 1988 GT Pro Series. Factory fast cats like Dave Milham and his team mate Robert Swick rely on the GT Pro Series to take home the gold. This GT racer is just as well equipped for high tech urban assaults as it is for world-class competition. GT Power Series one piece cranks keep the price low and sealed bearing GT BMX hubs, Dia Compe brakes and a 4130 chromoly chassis raise performance to a new high. If the race to the 7-11 is as important as the race to the finish, start winning both on a Pro Series.
