Featuring CeramicSpeed grade 3 Silicon Nitride balls, these bearings offer exceptional smoothness and performance thanks to their microscopic matching with hardened steel raceways, polished to perfection. Reinforced polyamide cages keep the balls securely in place, while non-contact seals protect against dirt and moisture, making these bearings a reliable choice for all cycling conditions.\u003c\/p\u003e\n\n\u003cp\u003eOptimized with a low viscosity CeramicSpeed “Blue Grease,” these bearings reduce friction significantly, enhancing power transfer and extending bearing life. Whether you ride road, time trial, triathlon, track, cyclocross, or mountain bike disciplines, these bearings deliver consistent, high-efficiency performance. Their superior construction results in a bearing that is smoother, harder, and lighter than standard steel alternatives, ensuring you get the most out of every pedal stroke.\u003c\/p\u003e\n\n\u003cp\u003eEach bearing undergoes rigorous hand inspection four times during assembly, confirming the perfect match of all components. The CeramicSpeed balls outperform industry standards—they are 400% smoother, 128% harder, and 58% lighter than typical steel balls, and they surpass other ceramic balls by being 15% harder, handling 99% higher loads, and maintaining 100% smoother operation. With dimensions precisely set at an inner diameter of 20 mm, outer diameter of 32 mm, and width of 7 mm, this bearing is engineered for optimal fit and function.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eEnhancing power transfer efficiency across all cycling disciplines\u003c\/li\u003e\n  \u003cli\u003eReducing friction to improve pedal smoothness and rider comfort\u003c\/li\u003e\n  \u003cli\u003eIncreasing bearing lifespan with superior materials and coatings\u003c\/li\u003e\n  \u003cli\u003eResisting dirt and moisture infiltration thanks to non-contact seals\u003c\/li\u003e\n  \u003cli\u003eProviding consistent performance in road, TT, triathlon, track, cyclocross, and MTB\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 20 mm inner and 32 mm outer diameter dimensions\u003c\/li\u003e\n  \u003cli\u003eUse in environments with extreme contamination beyond typical cycling conditions\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty industrial machinery beyond cycling component specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the CeramicSpeed coating improve bearing performance?\u003c\/strong\u003e\u003cbr\u003eThe coating reduces friction and wear, enhancing smoothness and extending the lifespan of the bearing under cycling conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan these bearings be used in all types of bicycles?\u003c\/strong\u003e\u003cbr\u003eYes, they are suitable for road, time trial, triathlon, track, cyclocross, and mountain bikes, offering versatile performance benefits.\u003c\/p\u003e","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":45499479949487,"sku":"101238","price":164.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/1674556985-99924100.jpg?v=1768523626","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/ceramicspeed-coated-single-bearing-61804-6804-for-high-performance-cycling","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
