Meticulously engineered for cyclists who demand the absolute best, this premium upgrade from the transmission experts at CEMA is designed to sign... moreificantly reduce drivetrain friction, enhance shifting precision, and provide unparalleled durability. By replacing your stock derailleur pulleys, you unlock wattage savings and a noticeably smoother, quieter, and more efficient ride. Experience a new level of performance where every pedal stroke is maximized, allowing you to conquer climbs and accelerate on the flats with newfound speed.These jockey wheels are the pinnacle of bearing technology. Featuring full ceramic bearings, both the bearing races and the balls are made from advanced ceramic material. This results in an incredibly low-friction system that spins with silky-smooth rotation, far surpassing standard steel or even hybrid-ceramic bearings. The inherent hardness and corrosion-proof nature of full ceramic bearings also mean they last significantly longer, resisting wear and contamination from dirt, water, and grime, ensuring consistent performance ride after ride, no matter the conditions.Key Benefits:* Maximum Frictional Reduction: The full ceramic bearing system minimizes rotational drag in your derailleur, saving precious watts and translating more of your power directly to the rear wheel.* Enhanced Shifting Performance: The derailleur pulley bodies are precision-machined from high-grade 7075 T6 aluminum. This creates a stiff and robust structure that eliminates flex, resulting in crisper, faster, and more decisive gear changes, especially under load.* Exceptional Durability and Longevity: Full ceramic bearings are harder, more resistant to corrosion, and require less maintenance than traditional bearings. Paired with a durable aluminum body, these jockey wheels are built to withstand the rigors of competitive racing and aggressive trail riding.* Lightweight and Stylish: Crafted from lightweight materials and available in anodized black or red, this pulley set adds a touch of professional-grade style to your bike while contributing to overall weight reduction.While this specific set is optimized for modern 12-speed systems, it represents CEM´s broader commitment to drivetrain excellence. CEMA provides a wide array of upgrade solutions, including options with SRC ceramic or stainless steel bearings and bodies made from carbon-reinforced plastic, suitable for a vast range of Shimano (9-10-11 speed) and SRAM (10-11 speed) road and MTB derailleurs.Technical Specifications* Product: CEMA Sram Eagle Full Ceramic Jockey Wheel Set* Category: Spare Parts* Subcategory: Transmission* Set Includes: Upper and Lower Pulley Wheels* Bearing Type: Full Ceramic* Body Material: High-Strength 7075 T6 Aluminium* Primary Compatibility: SRAM Eagle 12-speed
