Featuring super smooth CeramicSpeed grade 3 Silicon Nitride balls, this bearing is engineered for minimal friction and enhanced durability. The hardened steel raceways are polished to an ultra-smooth finish and perfectly matched to the ceramic balls within microns, delivering a seamless rotation that elevates your cycling experience.\u003c\/p\u003e\n\n\u003cp\u003eDesigned with a reinforced polyamide cage and optimized with CeramicSpeed’s exclusive low viscosity “Blue Grease,” this bearing reduces friction and extends service life. Non-contact seals protect against dirt and moisture, making it ideal for any cycling discipline—whether you ride Road, TT, Triathlon, Track, Cross, or MTB. The result is superior power transfer, smoother rides, and a bearing that outlasts conventional steel alternatives.\u003c\/p\u003e\n\n\u003cp\u003eEach bearing undergoes rigorous quality checks during assembly, ensuring flawless performance. The CeramicSpeed balls are 400% smoother, 128% harder, and 58% lighter than standard steel balls, and surpass competing ceramic balls by being 15% harder, capable of handling 99% higher loads, and 100% smoother. This bearing’s dimensions—15mm inner diameter, 28mm outer diameter, and 7mm width—make it a perfect upgrade for your wheels and hubs, maximizing efficiency and longevity.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing friction for smoother and more efficient cycling performance\u003c\/li\u003e\n  \u003cli\u003eEnhancing power transfer for improved speed and responsiveness\u003c\/li\u003e\n  \u003cli\u003eWithstanding high loads and harsh conditions across various cycling disciplines\u003c\/li\u003e\n  \u003cli\u003eProlonging bearing life with advanced materials and optimal lubrication\u003c\/li\u003e\n  \u003cli\u003eProviding reliable protection against dirt and moisture with effective sealing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eApplications outside of cycling components where different bearing specifications are required\u003c\/li\u003e\n  \u003cli\u003eEnvironments with extreme contamination or debris beyond the protection of non-contact seals\u003c\/li\u003e\n  \u003cli\u003eUse in setups incompatible with the 15mm inner diameter or 28mm outer diameter dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCan this bearing be used in all types of bikes?\u003c\/strong\u003e\u003cbr\u003eYes, the CeramicSpeed Single Bearing 61902 is suitable for a wide range of cycling disciplines including Road, TT, Triathlon, Track, Cross, and MTB.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does CeramicSpeed's \"Blue Grease\" improve the bearing?\u003c\/strong\u003e\u003cbr\u003eThe low viscosity \"Blue Grease\" minimizes friction inside the bearing, enhancing smoothness and significantly extending the bearing's lifespan.\u003c\/p\u003e","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":45499479556271,"sku":"101266","price":79.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/1564409242-46343100.jpg?v=1768523610","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/ceramicspeed-single-bearing-61902-6902-for-high-performance-cycling-components","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
