CERAMICSPEED OSPW rear derailleur cage system | SRAM Road AXS
CeramicSpeed's Oversized Pulley Wheel System (OSPW) is the logical consequence of minimizing friction. Due to the large derailleur pulleys with 15 teeth at the top and 19 teeth at the bottom, the wrap radii of the chain are significantly reduced, which is noticeable in the lower friction. In addition, the larger rear derailleur rollers offer a longer service life than other commercially available systems.
Technically, the OSPW system is equipped with high-performance bearings and special ceramic balls made of third-grade silicon nitrite (best grade achieved for ceramic bearings). The ball bearing cage is made of reinforced polyamide, with a hardened steel race and polished groove. The CeramicSpeed bearing balls are 15% harder, 100% smoother and 99% more resilient than standard ceramic balls. CeramicSpeed bearings are considered the best ceramic bearings in the world.
The bearing cage is made of carbon fibers reinforced with polyamide so that the forces can be better distributed and absorbed and your rear derailleur works perfectly even in the most adverse conditions.
It is important to properly lubricate the bearings to maintain performance and longevity. Simply apply oil to the bearing seals, allowing the oil to penetrate the bearing. Do this whenever you lubricate the chain, or after you wash your bike, or after riding in wet and muddy conditions.
When travelling, please remember to dismantle the entire rear derailleur, as very few bicycle transport bags offer enough space for the OSPW system. This OSPW system only fits SRAM Road AXS rear derailleurs!
