OSPW System for Shimano Coated black

Designed and fully developed by CeramicSpeed, the derailleur cage is oversized to optimize bike performance. Indeed, the speed changes will be made more efficiently and faster so that the rider has the right speed at all times, regardless of the terrain on which he ventures. High quality aluminum pulleys are equipped with CeramicSpeed ​​bearings that significantly reduce friction. This will allow the cyclist to save energy. The energy saving of the system reaches 30 to 60% compared to standard cages. In addition, the OSPW system has a lifespan that lasts 3 to 5 times longer than standard pulleys commonly used on the market. The system is available in two choices, one compatible with the Ultegra models (6700, 6770, 6800, 6870, 8000, 8050) and the Dura-Ace models (7900, 7970, 9000, 9070), 10 and 11 speeds and the electric units
