Fully hand-assembled in Denmark, this bearing uses \u003cstrong\u003eGrade 3 silicon nitride balls\u003c\/strong\u003e matched micron by micron with ultra-smooth hardened steel races. The ceramic balls are 400% smoother and 128% harder than standard steel bearings, ensuring exceptional performance in any conditions. The reinforced polyamide cage keeps the balls perfectly positioned, while the \u003cstrong\u003elow-viscosity Blue Grease lubricant\u003c\/strong\u003e minimizes friction and significantly extends the component’s service life.\u003c\/p\u003e\n\u003ch3\u003eUniversal compatibility and stringent quality control\u003c\/h3\u003e\n\u003cp\u003eThis \u003cstrong\u003e17x30x7mm bearing\u003c\/strong\u003e is designed to fit any cycling discipline: road, time trial, triathlon, track, cyclocross and mountain bike. The \u003cstrong\u003enon-contact seals\u003c\/strong\u003e effectively protect against dirt and moisture, maintaining performance over time. Every bearing undergoes four manual checks during assembly to ensure the perfect matching of all components. Compared with other ceramic balls on the market, CeramicSpeed balls are 15% harder, withstand loads that are 99% higher and offer 100% greater smoothness, confirming the product’s technical superiority.\u003c\/p\u003e\n\u003ch3\u003ePerformance benefits and long-lasting durability\u003c\/h3\u003e\n\u003cp\u003eThe use of \u003cstrong\u003elightweight ceramic balls\u003c\/strong\u003e reduces overall weight by 58% compared with traditional bearings, helping improve acceleration and the bike’s responsiveness. \u003cstrong\u003eLow friction\u003c\/strong\u003e translates directly into better power transfer, allowing cyclists to make the most of every pedal stroke. The combination of premium materials and advanced manufacturing technology ensures \u003cstrong\u003esuperior durability\u003c\/strong\u003e, reducing the frequency of maintenance and replacement. This bearing is a long-term investment for those who refuse to compromise on quality and mechanical performance.\u003c\/p\u003e\n\u003ch3\u003eTechnical features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInner diameter: 17 mm\u003c\/li\u003e\n\u003cli\u003eOuter diameter: 30 mm\u003c\/li\u003e\n\u003cli\u003eWidth: 7 mm\u003c\/li\u003e\n\u003cli\u003eBalls: \u003cstrong\u003eGrade 3 silicon nitride\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eRaces: ultra-smooth hardened steel\u003c\/li\u003e\n\u003cli\u003eCage: reinforced polyamide\u003c\/li\u003e\n\u003cli\u003eLubricant: \u003cstrong\u003eBlue Grease\u003c\/strong\u003e low-viscosity grease\u003c\/li\u003e\n\u003cli\u003eSeals: non-contact\u003c\/li\u003e\n\u003cli\u003eAssembly: hand-assembled in Denmark\u003c\/li\u003e\n\u003cli\u003eApplications: road, MTB, track, triathlon, cyclocross\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u0026nbsp;\u003c\/p\u003e","brand":"Ceramicspeed","offers":[{"title":"One size \/ Grey","offer_id":54291670532442,"sku":"101274","price":89.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7139\/6534\/files\/cera.png?v=1781164051","url":"https:\/\/www.all4cycling.com\/en\/products\/cuscinetto-ceramicspeed-17x30x7mm-ceramico","provider":"All4cycling ","version":"1.0","type":"link"}
