UNION CB-311 Ceramic LLB Bearings | High-Performance Hub UpgradeElevate your ride with the UNION CB-311 Ceramic LLB Bearings, the ultimate performance upgrade for your bicycle hubs. Designed for cyclists who demand maximum efficiency, speed, and durability, these premium spare parts are engineered to significantly reduce friction and enhance the overall performance of your wheelset. Whether you are a competitive racer looking for every possible advantage or a dedicated enthusiast seeking a smoother, faster, and more reliable ride, the CB-311 bearings deliver a tangible improvement you can feel from the very first pedal stroke.The core of these exceptional bearings lies in their advanced hybrid construction. By pairing incredibly hard and perfectly round Silicon Nitride balls with robust, precision-ground CrMo steel rings, the CB-311 achieves a level of performance that conventional steel bearings cannot match. This design minimizes rolling resistance, allowing your wheels to spin more freely and maintain momentum for longer, translating directly into higher speeds and reduced effort on the road or trail.Key Benefits:* Unmatched Rolling Efficiency: Experience a dramatic reduction in friction thanks to the superior properties of ceramic balls. Enjoy higher speeds and conserve energy on long rides, climbs, and sprints.* Exceptional Durability and Longevity: The extreme hardness of the Si3N4 balls resists wear and deformation far better than steel, ensuring these bearings maintain their high-performance characteristics for an extended lifespan with minimal maintenance.* Superior All-Weather Performance: The innovative LLB non-contact rubber seals provide an excellent barrier against dust, water, and grime without adding the drag associated with traditional contact seals. This smart design protects the bearing´s internals while preserving its low-friction advantage.* High-Precision Engineering: Manufactured to a strict ABEC-5 tolerance, these bearings guarantee exceptional concentricity and smoothness, eliminating play and vibration for a stable and predictable ride, especially at high speeds.These high-performance Bearings are meticulously crafted with components selected for their specific performance attributes. The lightweight and durable Nylon cage ensures perfect ball spacing for optimal load distribution and smooth operation under demanding conditions. Furthermore, each bearing is pre-lubricated with premium Kyodo Yushi Multemp PS2 grease, a high-performance fat known for its excellent stability, water resistance, and low-friction properties, ensuring peak performance right out of the box.Upgrade your hubs with the UNION CB-311 and transform your cycling experience. It´s not just a replacement part, it´s a direct investment in speed, efficiency, and long-lasting quality.Model:CB-311.- Measure:7x17x5.- Rings:CrMo.- Balls:Si3N4 Silicon Nitride (HRC 75-89).- Cage:Nylon.- Sealing:Rubber LLB (non-contact).- Fat:Multemp PS2 (Kyodo Yushi).- Tolerance:ABEC-5. tradeinn Bikeinn
