High-smoothness CeramicSpeed silicon nitride balls of grade 3 are (to the micrometer) combined with hardened steel raceways that feature an ultra-fine polished groove. The balls are held in place by a reinforced polyamide cage. Each bearing is optimized with a low-viscosity CeramicSpeed \"Blue Grease\" to minimize friction and increase bearing lifespan. Contactless seals complete the bearings and keep dirt and moisture out.\u003c\/p\u003e\u003cp\u003eCeramicSpeed bearings can be used for all cycling disciplines: road, time trial, triathlon, track, cyclocross, and MTB. The benefits are ultra-low friction, better power transfer, and increased bearing lifespan.\u003c\/p\u003e\u003cp\u003eDuring the manufacturing process, we check each bearing four times by hand to ensure that all parts are perfectly matched.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCeramicSpeed balls are 400% smoother, 128% harder, and 58% lighter than the standard steel balls commonly used in cycling\u003c\/li\u003e\n\u003cli\u003eCompared to other ceramic balls in the industry, CeramicSpeed balls are 15% harder, withstand 99% higher loads, and are 100% smoother\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSpecifications\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eInner diameter: 15.0\u003c\/li\u003e\n\u003cli\u003eOuter diameter: 21.0\u003c\/li\u003e\n\u003cli\u003eWidth: 4.0\u003c\/li\u003e\n\u003cli\u003eNet weight: 3.05 g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CeramicSpeed","offers":[{"title":"Coated","offer_id":57988795236616,"sku":"CER260229","price":141.34,"currency_code":"EUR","in_stock":false},{"title":"Standard","offer_id":57988795269384,"sku":"CER260229.1","price":90.5,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/7085\/1592\/files\/101215_101214.png?v=1781194004","url":"https:\/\/bikimailorder.com\/en-cz\/products\/ceramic-speed-61702-6702","provider":"Bike-Mailorder","version":"1.0","type":"link"}
