PBR Standard Steel Sprocket 2065 - 420 (manufacturer's ref: 2065 13 18NC): drive sprocket designed for 420 pitch chain transmission. A simple and robust replacement part for urban small-displacement bikes and cross machines that use a 13-tooth front sprocket.

• Material: steel
• Number of teeth: 13
• Chain pitch: 420
• Version: standard sprocket
• Brand: PBR

This PBR sprocket features standard dimensions for direct mounting on 420 transmissions. Choosing a standard steel sprocket offers good wear resistance against the demands of daily use or cross outings, while remaining easy to maintain. By changing the number of teeth on the sprocket, you affect the gear ratio of the machine: a smaller sprocket favours acceleration, while a larger one increases top speed — be sure to check the impact on the chain and the crown.

Common compatibilities:

• GAS GAS TXT ROOKIE 50 (2005 - 50 cc)
• DERBI SENDA 50 SM (1999 - 50 cc)
• GAS GAS EC 50 ROOKIE (2005 - 50 cc)

Before installation, check the bore diameter, the number of splines, and the chain/crown alignment. Follow regular maintenance: remove dirt, lubricate, and check chain tension to preserve the longevity of the transmission.
