Product Description
CEMA 105/Ultegra Full Ceramic Jockey Wheel Set | 12-Speed OS UpgradeUnleash the true potential of your Shimano drivetrain with the CEMA Full Ceramic Oversized Jockey Wheel Set. Designed specifically for discerning cyclists using the latest Shimano 105 R7150 and Ultegra R8100 12-speed groupsets, this premium pulley set is the ultimate upgrade for reducing friction, maximizing power transfer, and achieving unparalleled shifting smoothness. Elevate your ride from a standard setup to a high-performance system engineered for efficiency and durability.The core of this upgrade lies in its exceptional bearing technology. By utilizing full ceramic bearings, which feature both ceramic balls and races, this system drastically reduces rotational friction compared to standard steel or hybrid-ceramic bearings. This translates into tangible gains on the road, saving you precious watts with every pedal stroke and allowing more of your power to drive you forward. Furthermore, the inherent properties of full ceramic make these bearings incredibly resistant to corrosion and wear, ensuring long-lasting, consistent performance in all weather conditions, from dry summer days to wet and gritty winter rides.Efficiency is further enhanced by the oversized pulley design. The 12-tooth upper and 14-tooth lower pulley configuration creates a straighter, more direct chain path as it moves through the derailleur cage. This reduces the articulation angle of each chain link, significantly decreasing friction and mechanical drag. The result is a quieter, smoother, and more efficient drivetrain that feels noticeably faster and more responsive.Each pulley is meticulously crafted for precision and strength. The body is CNC machined from a solid block of high-grade 7075 T6 aluminum, ensuring perfect concentricity, a robust structure, and light weight. This precision engineering guarantees crisp, accurate shifting under load and contributes to the overall durability of your transmission. Engineered as a direct replacement part, this set offers a perfect, hassle-free fit for your stock derailleur cage, making the installation process straightforward for any experienced mechanic.Whether you are a competitive racer seeking every possible marginal gain or a dedicated enthusiast who demands the smoothest and most efficient ride possible, the CEMA Full Ceramic Jockey Wheel Set is a high-impact upgrade that delivers measurable results.Jockey Wheels Technical Specifications:Cema 12S pulley set (OS 12-14T) 105/Ultegra Aluminum Black Full Ceramic.Pulley set for 105/Ultegra 12-speed derailleurs.- Full ceramic bearings.- CNC machined 7075 T6 aluminum body.- Compatible with Ultegra R8100 and 105 R7150 12-speed derailleurs.Additional Details:* Product: CEMA 105/Ultegra Full Ceramic Jockey Wheel Set* Bearing Type: Full Ceramic (Ceramic Balls and Races)* Pulley Configuration: Oversized (OS) - 12-Tooth (Upper Guide Pulley) & 14-Tooth (Lower Tension Pulley)* Compatibility: Designed exclusively for Shimano Ultegra R8100 and Shimano 105 R7150 12-Speed rear derailleurs.* Category: Spare Parts* Subcategory: Transmission
