CERAMICSPEED OSPW rear derailleur cage system Aero Coated | SRAM Red AXS / Force AXS
Is it still possible to perfect the already fastest rear derailleur cage system? Ceramicspeed asked itself this question and worked on a solution together with the aerodynamics experts from Drag2Zero. And it says: It works. An almost closed cage encloses the jockey wheels and the guide plates and ensures that the air can flow past unhindered. In addition, braking turbulence is avoided. Numerous tests in the wind tunnel showed that the air resistance could be reduced by up to 60% compared to conventional rear derailleurs.
The proven Oversized Pulley Wheel System from Ceramicspeed continues to work under the “shell” and ensures a significant reduction in 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 passing through the cage, which is noticeable in the lower resistance. In addition, the enlarged wheels 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). These balls are 15% harder, 100% smoother and 99% more resilient than those of other manufacturers.
Compared to the already high-quality standard bearings from Ceramicspeed, the “Coated” version has a wafer-thin protective layer applied to the bearing rings. As a result, the latter become even harder, have a life cycle that is 60% longer and have even lower rolling resistance. Therefore, Ceramicspeed ball bearings are considered the best 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.
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!
