Each bearing uses ultra-smooth grade 3 Silicon Nitride balls, matched to within microns with hardened steel raceways that feature a highly polished groove. The balls are retained by a reinforced polyamide cage for optimal performance.\u003c\/p\u003e\n\n\u003ch2\u003ePerformance and Longevity\u003c\/h2\u003e\n\n\u003cp\u003eEvery bearing is optimised with low-viscosity CeramicSpeed “Blue Grease” to minimise friction and extend bearing life. Non-contact seals keep dirt and moisture out, ensuring consistent performance across all cycling disciplines including Road, TT, Triathlon, Track, Cyclocross, and MTB. The result is lower friction, improved power transfer, and increased longevity.\u003c\/p\u003e\n\n\u003ch2\u003ePrecision Matched\u003c\/h2\u003e\n\n\u003cp\u003eEach bearing is inspected by hand four times during the building process to guarantee all components are perfectly matched and assembled to the highest standard.\u003c\/p\u003e\n\n\u003ch2\u003eMaterial Advantages\u003c\/h2\u003e\n\n\u003cp\u003eCeramicSpeed Balls are 400% smoother, 128% harder, and 58% lighter than standard steel balls used in most bicycle bearings.
