The Ceramicspeed Shimano 9100 Coated Aero is a nearly enclosed cage that houses the jockey wheels and guide plates, ensuring that air can flow unimpeded. Additionally, braking turbulence is prevented. Extensive wind tunnel testing demonstrated that air resistance could be reduced by up to 60% compared to conventional rear derailleurs.
The OSPW system is equipped with high-performance bearings and special ceramic balls made of third-grade silicon nitride (the highest grade achieved for ceramic bearings). These balls are 15% harder, 100% smoother, and 99% more durable than those from other manufacturers.
Compared to Ceramicspeed’s standard high-quality bearings, the “Coated” version features a very thin protective layer applied to the bearing rings. As a result, the rings become even harder, have a 60% longer service life, and exhibit even lower rolling resistance. Therefore, Ceramicspeed ball bearings are considered the best in the world.
The bearing cage is made of carbon fiber, which has been reinforced with polyamide so that forces are better distributed and absorbed, and your derailleur operates flawlessly even under the most adverse conditions.
Ceramicspeed uses only the best materials and the latest technologies in production to consistently 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% perfect fit. So you really only use the best on your bike!
