Designed with super smooth CeramicSpeed grade 3 Silicon Nitride balls, these bearings are matched within microns to hardened steel raceways featuring ultra-smooth polished grooves. This combination ensures minimal friction, optimal power transfer, and a remarkable increase in bearing longevity.\u003c\/p\u003e\n\n\u003cp\u003eEach bearing incorporates a reinforced polyamide cage that securely holds the balls in place, while the low viscosity CeramicSpeed “Blue Grease” minimizes resistance and extends service life. Non-contact seals provide effective protection against dirt and moisture, making these bearings ideal for a wide array of cycling disciplines including Road, TT, Triathlon, Track, Cyclocross, and MTB.\u003c\/p\u003e\n\n\u003cp\u003eEvery bearing undergoes four rigorous hand inspections during assembly to guarantee perfect matching of all components. Compared to standard steel bearings, CeramicSpeed balls are 400% smoother, 128% harder, and 58% lighter. They also outperform other ceramic balls with 15% greater hardness, 99% higher load capacity, and 100% smoother operation, delivering superior performance and durability.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing friction for enhanced power efficiency on every ride\u003c\/li\u003e\n  \u003cli\u003eIncreasing bearing lifespan through advanced materials and lubrication\u003c\/li\u003e\n  \u003cli\u003eProviding reliable performance across multiple cycling disciplines\u003c\/li\u003e\n  \u003cli\u003eEnsuring consistent smoothness for improved wheel rotation and speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eUse in applications outside of cycling components and wheels\u003c\/li\u003e\n  \u003cli\u003eEnvironments with extreme contamination beyond standard dirt and moisture\u003c\/li\u003e\n  \u003cli\u003eHeavy industrial machinery requiring different bearing specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCan these bearings be used in mountain biking?\u003c\/strong\u003e\u003cbr\u003eYes, CeramicSpeed bearings are designed to perform excellently in MTB conditions with protection against dirt and moisture.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do these bearings improve cycling performance?\u003c\/strong\u003e\u003cbr\u003eThey reduce friction and increase power transfer efficiency, allowing for smoother, faster rides with less effort.\u003c\/p\u003e","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":45499479589039,"sku":"101230","price":79.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/1564409223-40254300.jpg?v=1768523615","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/ceramicspeed-single-bearing-61803-6803-for-high-performance-cycling","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
