Details

This bike is for somewhat smaller riders with a 19.5" top tube and 20x2.3" tyres. You still get the tough Hi-Ten steel frame, forks and 8.5" rise bars. The 3 Piece forged crankset is paired with a 25t sprocket for a reliable ride. As with most Academy bikes it is built to give you great value so that you can get the most out of every ride.
