CERAMICSPEED OSPW RS 5 Spoke Shimano 9250/8150 Jockey Wheel System
Elevate your drivetrain to the pinnacle of performance with the CERAMICSPEED OSPW RS 5 Spoke System, meticulously engineered for Shimano Dura-Ace 9250 and Ultegra 8150 12-speed Di2 rear derailleurs. This system is not just an upgrade; it´s a fundamental transformation of your bike´s efficiency, speed, and aesthetics, born from years of research and development in the pro-peloton. Designed for the discerning cyclist who refuses to compromise, the OSPW RS (Raceday Spec) represents the new gold standard in drivetrain optimization, delivering tangible watt savings and an unparalleled riding experience.
The CERAMICSPEED OSPW RS 5 Spoke Gear System is a high-performance upgrade for Shimano 9250 and 8150 electronic groupsets. This system features oversized pulley wheels with CeramicSpeed bearings and an aerodynamic carbon fiber cage to reduce friction and improve efficiency. The red color adds a pop of style to your bike, while the spare parts included ensure easy maintenance and longevity of the system. Enhance your bike´s transmission with this top-of-the-line gear system from CERAMICSPEED.
At the heart of the system are the oversized 13-tooth upper and 19-tooth lower pulley wheels. This configuration significantly reduces the angle at which the chain articulates as it moves through the derailleur, dramatically lowering friction and saving precious watts with every pedal stroke. The innovative 5-spoke pulley wheel design further enhances performance by increasing stiffness for lightning-fast, precise shifting while also improving aerodynamics.
The handcrafted carbon fiber cage provides a lightweight yet incredibly rigid platform, ensuring your chain remains perfectly aligned under the highest loads of a sprint or a steep climb. Its aerodynamic profile has been refined to minimize drag, contributing to an overall faster setup. This system is a statement of intent, proving that every detail has been considered in your quest for speed.
