Born from PBR's experience in competition, this standard steel C45 sprocket is aimed at riders looking for a reliable replacement for their final drive. Designed for drivetrains equipped with a 525 chain, it follows standard dimensions for easy and hassle-free installation.

This sprocket installs in place of the original part on transmissions accepting the 525 pitch. It is suitable for road use and roadsters seeking a robust replacement part for the gearing and chain drive. For a clean installation, check the condition of the pinion and chain: replacing the sprocket simultaneously with a worn chain and pinion prevents premature wear.
