This is the Rocker Sprocket Ultra-Lite Series Quick Change Sprocket. Rocket Sprocket has been manufacturing sprockets in the USA since 1992. The premier feature of the Rocket Sprocket is the patented quick change system. It allows the sprocket to be removed without completely removing the retaining nuts or chain guard. Just loosen the retaining nuts and the sprocket halves will lift and rotate off the hub. Or if preferred you can use it with the standard 6 bolt pattern. Very light weight and proudly made in the USA.
