{"product_id":"ceramic-speed-r4","title":"R4","description":"\u003cp\u003eAll CeramicSpeed bearings are handcrafted in Denmark. Ultra-smooth CeramicSpeed silicon nitride balls of grade 3 are combined (to the micrometer) with hardened steel raceways that feature an ultra-fine polished groove. The balls are held in position 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\n\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\n\u003cp\u003eDuring the manufacturing process, we check each bearing by hand four times to ensure that all parts are perfectly matched.\u003c\/p\u003e\n\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\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInner diameter: 6.35\u003c\/li\u003e\n\u003cli\u003eOuter diameter: 15.875\u003c\/li\u003e\n\u003cli\u003eWidth: 4.978\u003c\/li\u003e\n\u003cli\u003eNet weight: 3.55 g\u003c\/li\u003e\n\u003cli\u003eInner diameter: 6.35\u003c\/li\u003e\n\u003cli\u003eOuter diameter: 15.875\u003c\/li\u003e\n\u003cli\u003eWidth: 4.978\u003c\/li\u003e\n\u003cli\u003eNet weight: 3.55 g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CeramicSpeed","offers":[{"title":"Standard","offer_id":58007535649032,"sku":"CER260343","price":93.49,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/7085\/1592\/files\/101893.png?v=1781272971","url":"https:\/\/bikimailorder.com\/en-dk\/products\/ceramic-speed-r4","provider":"Bike-Mailorder","version":"1.0","type":"link"}
