Rennen Aluminium sprocket 4 bolts

Made from 7075 aluminium, the RENNEN chainring is unique thanks to its decimal tooth design, which is achieved by making slight adjustments to the circumference of the chainring. This allows you to modify your gear ratio by increments of teeth depending on your needs for the BMX track you'll be riding on. It is designed to be mounted on a 4-bolt crankset.
