CeramicSpeed grade 3 Silicon Nitride ceramic balls deliver markedly lower rolling friction than the standard steel bearings they replace - and they keep running smoothly for far longer. For road riders chasing efficiency on top-tier framesets, it is a small change that compounds across every ride.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eConstruction \u0026amp; Materials\u003c\/strong\u003e\u003cbr\u003e\nEach cup is precision machined from high-grade aluminium to the tight tolerances the BB86 standard demands, then hand-assembled with CeramicSpeed's signature grade 3 Silicon Nitride ceramic balls. Coated bearing options gain an additional 60% bearing life and a further 50% reduction in friction through CeramicSpeed's metallic surface treatment.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003cbr\u003e\nFits any frameset with a BB86 press-fit shell - 41mm bore, 86.5mm shell width.
