This is a genuine Sturmey-Archer 20T sprocket with the 3-spline fitting and a flat profile. It slides onto the splined driver of Sturmey-Archer hubs that use 3-spline sprockets, such as many of their coaster brake and internal gear hubs, and is held in place by a circlip.
Swapping sprockets is the simple way to change gearing on a hub-geared or single-speed coaster bike. A bigger sprocket makes pedalling easier for hills and stop-start riding, while a smaller one gives a taller gear for flat, faster roads. The chrome plating helps it resist rust on bikes that live outdoors.
