CERAMICSPEED OSPW rear derailleur cage system
The Oversized Pulley Wheel System from CERAMICSPEED is the logical consequence of minimizing friction. The large derailleur pulleys with 13 teeth at the top and 19 teeth at the bottom significantly minimize the movement of the chain links when running through the cage , which is reflected in less 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% more flexible and 99% more resilient than standard ceramic balls. CERAMICSPEED bearings are considered to be the best ceramic bearings worldwide.
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.
CeramicSpeed only uses the best materials and the latest technologies in production in order to always achieve the highest possible quality. All products are handmade in Denmark. No hydraulic presses are used during assembly. Manual assembly eliminates manufacturing tolerances and always guarantees a 100% fit. So that you really only use the best on your bike!
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, after washing the bike and after riding in wet/muddy conditions.
When travelling, please remember to dismantle the entire rear derailleur with an Allen key, as very few bicycle transport bags offer enough space for the OSPW system.
