This bearing features grade 3 Silicon Nitride ceramic balls, precision-matched within microns to hardened steel raceways that have an ultra-smooth polished groove. The reinforced polyamide cage securely holds the balls in place, while the low-viscosity CeramicSpeed \"Blue Grease\" optimizes friction reduction and extends bearing lifespan. Non-contact seals protect against dirt and moisture, ensuring consistent performance in all conditions.\u003c\/p\u003e\n\n\u003cp\u003eDesigned for versatility, this bearing is suitable for a wide range of cycling disciplines, including Road, TT, Triathlon, Track, Cyclocross, and MTB. The superior smoothness of CeramicSpeed balls—400% smoother, 128% harder, and 58% lighter than standard steel bearings—translates into enhanced power transfer and greater efficiency. Rigorous quality control with four manual inspections guarantees perfect matching for every bearing, providing durability and reliability you can trust.\u003c\/p\u003e\n\n\u003cp\u003eDimensions are precisely engineered to fit seamlessly, with an inner diameter of 12 mm, outer diameter of 21 mm, and width of 5 mm, making it a perfect component for hubs, spares, and accessories related to wheels and tyres.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing friction for smoother, more efficient cycling performance\u003c\/li\u003e\n  \u003cli\u003eEnhancing power transfer across various cycling disciplines\u003c\/li\u003e\n  \u003cli\u003eIncreasing bearing durability and lifespan under demanding conditions\u003c\/li\u003e\n  \u003cli\u003eProtecting internal components from dirt and moisture with non-contact seals\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 requiring bearings outside the specified 12 mm x 21 mm x 5 mm dimensions\u003c\/li\u003e\n  \u003cli\u003eUse in extremely abrasive environments without additional protective measures\u003c\/li\u003e\n  \u003cli\u003eSituations where standard steel bearings are preferred due to cost constraints\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 for mountain biking?\u003c\/strong\u003e\u003cbr\u003eYes, the CeramicSpeed Single Bearing Coated 61801 is suitable for MTB and other cycling disciplines, offering durability and superior performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the CeramicSpeed \"Blue Grease\" improve bearing life?\u003c\/strong\u003e\u003cbr\u003eThe low-viscosity grease minimizes friction and wear inside the bearing, significantly extending its lifespan compared to standard lubricants.\u003c\/p\u003e","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":45499479785647,"sku":"101222","price":124.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/1564409255-29707500.jpg?v=1768523634","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/ceramicspeed-coated-single-bearing-61801-6801-for-cycling-performance","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
