CRUPI enters the OS20 range by offering its new frame incorporating the characteristics of the Level model but in size OS20, the size of the wheels is the same diameter as the 20x1-1 / 8 '' or 20x1-3 / 8 '' wheels, this which makes them bigger but with the width of pro size rims therefore more resistant This makes the bike a little more stable and still considered a 20 inch bike! Like the Level, this 100% USA-made frame is constructed from high quality 6061-T6 butted aluminum with a tapered head tube, square section down tube that maintains frame strength and stiffness at the head tube level. and the bottom bracket while reducing weight

OS20 is not 22" diameter but larger 20" diameter. The OS20 is therefore a higher and larger diameter for stiffness and velocity. It was designed to offer more speed and less rolling resistance compared to the conventional 20 "diameter.
