This bearing features CeramicSpeed grade 3 Silicon Nitride balls, precisely matched within microns to hardened steel raceways that boast an ultra-smooth polished groove. The reinforced polyamide cage ensures the balls remain securely in place, while the low viscosity CeramicSpeed \"Blue Grease\" minimizes friction and extends the bearing's lifespan. Designed with non-contact seals, it effectively keeps dirt and moisture out, preserving optimal functionality over time.\u003c\/p\u003e\n\n\u003cp\u003eIdeal for a wide range of cycling disciplines including Road, TT, Triathlon, Track, Cyclocross, and MTB, this bearing delivers super low friction and enhanced power transfer, helping you get the most from every pedal stroke. The CeramicSpeed balls outperform standard steel alternatives by being 400% smoother, 128% harder, and 58% lighter. Compared to other ceramic balls on the market, they are 15% harder, endure 99% higher loads, and offer 100% smoother rotation, providing superior durability and efficiency.\u003c\/p\u003e\n\n\u003cp\u003eEvery bearing undergoes rigorous quality control, with four manual inspections during assembly to guarantee perfect matching of components. With an inner diameter of 12mm, outer diameter of 21mm, and width of 5mm, the CeramicSpeed Single Bearing 61801 is engineered to deliver precision and longevity in your bike’s components.\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\u003c\/li\u003e\n  \u003cli\u003eEnhancing power transfer to improve overall performance\u003c\/li\u003e\n  \u003cli\u003eProviding durable and lightweight bearing solutions\u003c\/li\u003e\n  \u003cli\u003eSuitable for multiple cycling disciplines including Road, TT, Tri, Track, Cross, and MTB\u003c\/li\u003e\n  \u003cli\u003eResisting dirt and moisture with advanced sealing technology\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 non-cycling applications that require different bearing specifications\u003c\/li\u003e\n  \u003cli\u003eEnvironments with excessive contamination beyond seal protection capabilities\u003c\/li\u003e\n  \u003cli\u003eApplications demanding bearings outside the specified size (12mm inner, 21mm outer, 5mm width)\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 on all types of bicycles?\u003c\/strong\u003e\u003cbr\u003eYes, CeramicSpeed Single Bearing 61801 is versatile and designed to work with Road, TT, Triathlon, Track, Cyclocross, and MTB bikes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the \"Blue Grease\" improve bearing performance?\u003c\/strong\u003e\u003cbr\u003eThe low viscosity CeramicSpeed \"Blue Grease\" reduces friction inside the bearing, leading to smoother rotation and increased durability over time.\u003c\/p\u003e","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":45965248725167,"sku":"101221","price":79.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/101221.jpg?v=1768532714","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/ceramicspeed-single-bearing-61801-6801-for-cycling-low-friction-durable","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
