Hand-built in Denmark, this bearing features grade 3 Silicon Nitride ceramic balls that are matched with hardened steel raceways, polished to an ultra-smooth finish. The reinforced polyamide cage ensures the balls stay perfectly aligned, enhancing durability and consistency during every ride.\u003c\/p\u003e\n\n\u003cp\u003eOptimized with CeramicSpeed’s exclusive low viscosity \"Blue Grease,\" this bearing minimizes friction and extends lifespan, while non-contact seals keep out dirt and moisture. Designed for versatility, the 61800 bearing excels across all cycling disciplines—from Road and TT to Track, Cross, and MTB—delivering smoother rotation, improved power transfer, and ultimately a more efficient ride.\u003c\/p\u003e\n\n\u003cp\u003eEach bearing undergoes rigorous quality checks, ensuring unparalleled precision and performance. CeramicSpeed balls are 400% smoother and significantly harder and lighter than standard steel counterparts, offering a competitive edge through reduced rolling resistance and increased load capacity. The compact dimensions of 10mm inner diameter, 19mm outer diameter, and 5mm width make it an ideal component for high-performance hubs and wheels.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eEnhancing power transfer by reducing rolling resistance\u003c\/li\u003e\n  \u003cli\u003eProviding long-lasting durability thanks to high-grade materials\u003c\/li\u003e\n  \u003cli\u003eMaintaining smooth operation across multiple cycling disciplines\u003c\/li\u003e\n  \u003cli\u003eResisting contamination with advanced non-contact seals\u003c\/li\u003e\n  \u003cli\u003eOffering a precise fit for high-performance wheel hubs\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 requiring sealed or grease-filled bearings with different specifications\u003c\/li\u003e\n  \u003cli\u003eHeavy machinery or non-cycling industrial uses\u003c\/li\u003e\n  \u003cli\u003eEnvironments with extreme contamination beyond standard cycling conditions\u003c\/li\u003e\n  \u003cli\u003eUse in components incompatible with the 61800 bearing 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 for mountain biking?\u003c\/strong\u003e\u003cbr\u003eYes, the CeramicSpeed 61800 bearing is suitable for MTB and all other cycling disciplines, offering excellent durability and smoothness on rough terrains.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the \"Blue Grease\" improve performance?\u003c\/strong\u003e\u003cbr\u003eThe low viscosity CeramicSpeed \"Blue Grease\" minimizes friction inside the bearing, leading to smoother rotation and longer bearing life compared to standard greases.\u003c\/p\u003e","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":45965248692399,"sku":"101220","price":79.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/101220.jpg?v=1768532740","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/ceramicspeed-61800-6800-single-bearing-for-high-performance-cycling-hubs","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
