Featuring CeramicSpeed grade 3 Silicon Nitride balls matched within microns to hardened steel raceways, these bearings offer an ultra-smooth polished groove for effortless rotation. The reinforced polyamide cage securely holds the balls in place, while the specially formulated low viscosity CeramicSpeed “Blue Grease” reduces friction and extends bearing life. Non-contact seals protect against dirt and moisture, guaranteeing reliability across all cycling disciplines.\u003c\/p\u003e\n\n\u003cp\u003eDesigned for versatility, the CeramicSpeed 61805 bearing excels in Road, TT, Triathlon, Track, Cyclocross, and MTB applications. Its advanced construction results in significantly lower friction, improved power transfer, and enhanced durability. Each bearing undergoes four rigorous quality checks by hand during assembly, ensuring precise matching of all components. The CeramicSpeed balls are remarkably 400% smoother, 128% harder, and 58% lighter than standard steel bearings, and outperform other ceramic balls with 15% greater hardness, 99% higher load capacity, and 100% smoother operation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing friction to maximize cycling efficiency\u003c\/li\u003e\n  \u003cli\u003eImproving power transfer for a more responsive ride\u003c\/li\u003e\n  \u003cli\u003eEnhancing bearing lifespan with superior materials and lubrication\u003c\/li\u003e\n  \u003cli\u003eProviding reliable performance across multiple cycling disciplines\u003c\/li\u003e\n  \u003cli\u003eProtecting internal components from dirt and moisture with non-contact seals\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eUse in applications outside cycling where specific bearing types are required\u003c\/li\u003e\n  \u003cli\u003eEnvironments with excessive contamination beyond typical cycling conditions\u003c\/li\u003e\n  \u003cli\u003eReplacing bearings of incompatible sizes or specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAre these bearings compatible with all bike hubs?\u003c\/strong\u003e\u003cbr\u003eThese bearings fit hubs with matching inner diameter 25mm, outer diameter 37mm, and width 7mm.
