Cema Shimano Full Ceramic Jockey Wheel Set

CEMA Shimano Full Ceramic Jockey Wheel Set | TransmissionElevate your drivetrain to its peak potential with the CEMA Shimano Full Ceramic Jockey Wheel Set. Designed for the discerning cyclist seeking every possible performance advantage, this oversized pulley wheel system is the ultimate upgrade for your transmission. Experience a tangible reduction in drivetrain friction, allowing you to convert more of your precious watts into pure speed. This is not just a replacement part, it´s a significant performance enhancement for your Shimano-equipped road bike, engineered to deliver a smoother, faster, and more efficient ride.The foundation of this system lies in its oversized design. By increasing the size of the jockey wheels, the chain is guided through a wider, more gradual arc as it passes through the derailleur cage. This significantly reduces chain articulation and the resulting friction at each link. The outcome is a noticeably smoother, more efficient power transfer from the pedals to the road, saving you critical energy on long rides and giving you a decisive edge when the pace quickens. Feel the difference with every pedal stroke as your drivetrain operates with unparalleled smoothness and quietness.At the heart of these exceptional jockey wheels are the full ceramic bearings. CEM´s SRC (Special Racing Ceramic) technology represents the pinnacle of bearing performance. Unlike traditional steel or hybrid-ceramic bearings, a full ceramic construction offers an incredibly low coefficient of friction, ensuring the wheels spin with almost complete freedom. This translates to maximum efficiency and superior durability. These advanced bearings are also highly resistant to corrosion and contamination, guaranteeing consistent, high-level performance in all weather conditions, ride after ride, with minimal maintenance.Precision engineered for excellence, the pulley wheel body is meticulously CNC-machined from a single block of high-grade 7075 T6 Aluminium. This advanced alloy provides an optimal balance of strength, stiffness, and low weight, ensuring crisp and accurate shifting even under maximum load. The durable, sleek black anodized finish not only adds a professional aesthetic to your derailleur but also provides an extra layer of protection against the elements, maintaining the system´s integrity and appearance for years to come. Upgrade your bike with CEMA and unlock the full performance of your Shimano transmission.Technical SpecificationsOversized pulley wheels set.- Compatibility: Specifically designed for Shimano 10 and 11-speed long cage rear derailleurs:- R7000 (105)- R8000 (Ultegra)- R9000 (Dura-Ace)- Bearing Type: Full Ceramic (SRC Special Racing Ceramic)- Jockey Wheels Body Material: CNC-machined 7075 T6 Aluminium- Colour: Black
