Thin Retainer Ring to suit clutch sprockets.

Suits all CSPR11 (11T #35) CSPR13P (13T 219P) and CSPR14P (14T 219P) clutch sprockets

The 11T #35, 13T 219 and 14T 219 sprockets are designed to run without the standard circlip and instead use this thin ring, and the thicker thrust washer CSPRTT.

Smaller sprockets such as the 11t #35, 13t, and 14t #219 are naturally thinner and more delicate than larger options. Because of this, their service life is usually shorter, especially when used in high-power or high-torque setups. To get the best performance and longevity, these sprockets need extra attention compared to larger sizes.

For best results, lightly polish the drive hub’s bearing sleeve with 600-grit wet/dry sandpaper so that the contact surface is as smooth as possible. Apply a thin film of high-grade, heavy wheel bearing grease inside the sprocket before use. After each session, disassemble the sprocket, clean thoroughly, and re-apply grease before reassembly.
