CeramicSpeed T61805 Cuscinetto a sfere rivestito 25x37x6mm

This CERAMICSPEED T61805 COATED bearing (25 x 37 x 6 mm) for the bottom bracket ensures incredible fluidity and maximum durability.

All CeramicSpeed bearings are handmade in Denmark. Super-smooth CeramicSpeed grade 3 silicon nitride balls are matched (in the micron range) to hardened steel raceways that have an ultra-smooth, polished groove.
This coated version has a unique metal coating covering the rings.
This treatment makes these components 75% harder than conventional steel, optimising corrosion resistance and offering lower friction than standard bearings.
