Featuring grade 3 Silicon Nitride ceramic balls, these bearings provide exceptional smoothness and durability. Each ball is precisely matched within microns to hardened steel raceways with an ultra-smooth polished groove, ensuring minimal friction and exceptional power transfer for your ride.\u003c\/p\u003e\n\n\u003cp\u003eThe reinforced polyamide cage securely holds the balls in place, while the innovative low viscosity CeramicSpeed “Blue Grease” reduces friction and extends bearing lifespan. Non-contact seals protect the internals from dirt and moisture, making these bearings suitable for any cycling discipline including Road, TT, Triathlon, Track, Cyclocross, and MTB. Experience longer-lasting performance with bearings that are not only 400% smoother but also 128% harder and 58% lighter than standard steel options.\u003c\/p\u003e\n\n\u003cp\u003eEach bearing undergoes four rigorous quality checks by hand during the assembly process to ensure perfect matching of all components. When compared to other ceramic balls available, CeramicSpeed Balls stand out by being 15% harder, handling 99% higher loads, and offering 100% smoother operation. Upgrade your cycling components with CeramicSpeed for enhanced efficiency and reliability.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing friction to improve power transfer and speed\u003c\/li\u003e\n  \u003cli\u003eExtending bearing life through high-quality materials and lubrication\u003c\/li\u003e\n  \u003cli\u003eProviding reliable performance across multiple cycling disciplines\u003c\/li\u003e\n  \u003cli\u003eWithstanding high loads due to superior ceramic ball hardness\u003c\/li\u003e\n  \u003cli\u003eMaintaining cleanliness and durability 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 sealed or maintenance-free bearings beyond standard cycling use\u003c\/li\u003e\n  \u003cli\u003eSituations where ceramic bearings’ higher cost is not justified by performance needs\u003c\/li\u003e\n  \u003cli\u003eHeavy industrial machinery outside of cycling components\u003c\/li\u003e\n  \u003cli\u003eEnvironments with extreme contamination beyond typical cycling conditions\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 all types of bicycles?\u003c\/strong\u003e\u003cbr\u003eYes, CeramicSpeed Single Bearing 61901 (6901) is designed for versatility and works well in Road, TT, Triathlon, Track, Cyclocross, and MTB bikes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the CeramicSpeed “Blue Grease” benefit the bearing?\u003c\/strong\u003e\u003cbr\u003e“Blue Grease” is a low viscosity lubricant that reduces friction, enhances smoothness, and significantly extends the life of the bearing by protecting it from wear and tear.\u003c\/p\u003e","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":45965248921775,"sku":"101261","price":79.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/101261.jpg?v=1768532728","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/ceramicspeed-single-bearing-61901-6901-high-performance-cycling-bearing","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
