Overview
About this bike
No need to break little Johnny's piggy bank—GT's Air is affordable and built to last. The hi-ten steel frame includes a downtube gusset for extra strength and includes removable rotor tabs if you plan to upgrade down the road. An aluminum rear U-brake, 3-piece chromoly cranks turning 25/9 gearing, and 8.375" bar supply the necessary bits for action. Take a breath of fresh—this Air's for you.
