High-smooth CeramicSpeed silicon nitride balls of grade 3 are combined (to the micrometre) 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 optimised with a low-viscosity CeramicSpeed \"Blue Grease\" to minimise 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 advantages 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 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: 35.0\u003c\/li\u003e\n\u003cli\u003eOuter diameter: 47.0\u003c\/li\u003e\n\u003cli\u003eWidth: 7.0\u003c\/li\u003e\n\u003cli\u003eNet weight: 25.5 g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CeramicSpeed","offers":[{"title":"Standard","offer_id":57988791501064,"sku":"CER260241","price":175.43,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/7085\/1592\/files\/101255.png?v=1781194012","url":"https:\/\/bikimailorder.com\/en-dk\/products\/ceramic-speed-61807-6807","provider":"Bike-Mailorder","version":"1.0","type":"link"}
