GT Air 20'' GT YellowThe GT Air is a Steel, Low Profile, Springfield Brake Compatible BMX bike. The majority of the bike is made up of steel, so while it may be a bit heavy it can take a heavy beating and still ride extremely well. The grips are GT’s Super Soft 155 mm with a removable plug at each end to match personal preference or to accommodate bar ends. The saddle is railed, meaning that on top of being able to adjust the seatpost up and down, the seat itself can be moved forwards or backwards for additional comfort. Available in Yellow and Gloss Transparent Black.038675203808
