RENNEN CHAINRING 4 BOLT BCD 104 BLUE

Hand Made in the USA from a machined 7075 Aluminum, the RENNEN chainring is unique thanks to the decimal toothing made from a slight modification of the circumference of the crown. This allows you to change your gear by fraction of teeth according to your needs in relation to the BMX track on which you are going to ride. It is designed to be mounted on a 4-bolt crankset.
