This blank spacer lets you run a different sized sprocket on your axle/crank setup

These are known as 22mm to 19mm because they make a 19mm axle the same size as a 22mm

22mm axles measure 23.75mm at the point where the chain ring is attached

This spacer enables 25 tooth front chain rings with a centre hole measurement of 23.8mm to be fitted to 19mm bottom bracket axles
