These hand-built Danish bearings feature ultra-hard coated steel raceways and lighter, harder CeramicSpeed Grade 3 Silicon Nitride balls, dramatically reducing friction for more speed and smoother rides. Optimized with low-viscosity "Blue Grease" and non-contact seals, they offer exceptional durability, corrosion resistance, and minimal drag. Experience a significant performance boost and long-lasting reliability with these precision-engineered hub upgrades. Upgrade Your Ride with CERAMICSPEED 61902-2RSF/HC5 Coated Hub BearingsExperience the pinnacle of cycling performance and durability with the CERAMICSPEED 61902-2RSF/HC5 Coated Bearings, the ultimate upgrade for your wheel hubs. Engineered for discerning cyclists who demand uncompromising speed, efficiency, and longevity, these bearings represent the zenith of drivetrain optimization. By significantly reducing friction, you unlock free speed and enjoy a smoother, more responsive ride on every journey.The defining feature of these elite bearings is the special coating applied to the hardened steel raceways. This unique metallic layer, just microns thin, makes the raceways 75% harder than standard steel. The result is a dramatic reduction in friction and a substantial increase in resistance to corrosion and wear, even when running with minimal lubrication. This technology ensures that your investment continues to pay dividends in performance and reliability, mile after mile.All CeramicSpeed Bearings are hand-built in Denmark, a testament to the brand´s commitment to unparalleled quality and precision. At the core of each bearing are the super smooth CeramicSpeed grade 3 Silicon Nitride balls. These ceramic balls are 58% lighter and significantly harder than traditional steel balls, contributing to faster acceleration and superior durability. Each set of balls is meticulously matched (within microns) with the hardened steel raceways that feature an ultra-smooth polished groove, creating a near-perfect rolling surface that minimises energy loss.To ensure optimal alignment and performance under load, the balls are held in place by a reinforced polyamide cage. This robust yet lightweight cage maintains perfect spacing between the balls, reducing friction and enhancing the bearing´s overall lifespan.Every bearing is optimised with a low viscosity CeramicSpeed Blue Grease to minimise friction and increase bearing life. This specialised lubricant is specifically formulated to complement the ceramic components, providing the lowest possible rolling resistance while offering excellent protection. To complete the system, non-contact seals complete the bearings, keeping dirt and moisture out. This intelligent seal design provides robust protection against the elements without creating the additional drag commonly associated with standard rubber seals, ensuring your speed is never compromised.Key Benefits:* Drastically Reduced Friction: Unlock free watts and achieve higher speeds with less effort.* Enhanced Durability: Coated raceways and ceramic balls offer an exceptionally long service life.* Superior Smoothness: Experience an incredibly smooth and responsive rolling feel from your hubs.* Corrosion Resistance: The unique coating protects against rust and contamination.* Hand-Built Quality: Meticulously assembled in Denmark for ultimate precision and reliability.Technical Specifications:* Product: CERAMICSPEED 61902-2RSF/HC5 Coated* Attribute: Bearings* Dimensions: 15x28x7 mm* Application: Hubs (Front / Rear)* Technology: Coated Hardened-Steel Raceways* Balls: CeramicSpeed Grade 3 Silicon Nitride* Cage: Reinforced Polyamide. tradeinn Bikeinn
