CERAMICSPEED OSPW System Coated Rear Derailleur Cage Shimano Dura Ace 9100 | Ultegra 8000
The Oversized Pulley Wheel System (OSPW) from CERAMICSPEED is the logical consequence of friction minimization. The oversized derailleur rollers with 13/19 teeth significantly reduce the chain's radii of curvature, resulting in less friction. In addition, the larger derailleur rollers offer a 3-5 times longer life than other commercially available systems.
With this system you save about 1.6 to 2.4 watts which was tested in an independent test of friction facts. This makes it a worthwhile investment for solo riders, triathletes and runners alike.
Technically, the OSPW system is equipped with high-performance bearings with special ceramic ball made of silicon nitride grade 3 (best achieved degree for ceramic bearings). The matching ball bearing cage is made of reinforced polyamide, with a race made of hardened steel with polished groove. This is additionally provided with a coating that further minimizes friction. The CERAMICSPEED bearing balls are 15% harder, 100% smoother and 99% stronger than standard ceramic balls. CERAMICSPEED bearings are considered the best ceramic bearings worldwide.
The bearing cage is made of carbon fiber reinforced with polyamide, so that the forces can be better distributed and absorbed and your rear derailleur is working properly.
A 3 micron thick coating of the raceways reduces the resistance during rotation and at the same time increases the service life.
CeramicSpeed uses only the best materials and the latest technologies to produce the highest quality possible. All warehouses are handmade in Denmark and installed in high-precision bearings manufactured in Europe. During assembly, no hydraulic presses are used.
Manual assembly eliminates manufacturing tolerances and guarantees a 100% fit. So that you really only the best thing on your bike!
It is important to maintain the performance and longevity to lubricate the bearings carefully. Simply apply oil to the seals of the bearings so that the oil can penetrate into the bearing. Do this each time when lubricating the chain, or after washing the wheel, or after driving in wet and muddy conditions.
When traveling, please remember to dismantle the complete rear derailleur with an Allen key, as few bicycle carrying bags provide sufficient space for the OSPW system.
