Description
Retaining ring for bicycle mechanisms and agricultural machinery for 35-36 mm shaft, 33 mm internal
Bicycle rear sprocket retaining ring (d33–35 mm, for three-spline fit)
Spring retaining ring for the rear sprocket (diameter 33–35 mm) for secure fixation of the driven sprocket on the driver (axle) of the rear hub of single-speed, road, and folding bicycles, as well as models with planetary hubs. The ring is installed in a special groove (recess) of the hub and holds the sprocket from longitudinal displacement and play under load.
Key Advantages and Features:
- Secure fixation: Spring steel provides high elasticity, ensuring the ring snaps tightly into the hub groove and does not come off due to vibrations.
- Anti-corrosion coating: Protected from moisture, dirt, and road reagents.
- Precise standard compliance: Perfectly fits the 33–35 mm groove diameter of classic coaster brake and planetary hubs.
- Easy installation: Easily installed and removed using a flathead screwdriver or a special snap ring plier.
Hub Compatibility:
- Road and single-speed hubs (Single Speed / Torpedo): Ukraina, Aist, Minsk, Desna, Salyut, KhVZ, PVZ, Velosteel, and their equivalents.
- Planetary hubs: Shimano Nexus (3, 7, 8 speeds), SRAM, Sturmey Archer.
