CeramicSpeed BB30 Bottom Bracket for Shimano Road Black - CoatedThe CeramicSpeed BB30 Bottom Bracket for Shimano Road is for BB30 frames that use a Shimano 24 mm spindle crankset. This CeramicSpeed BB uses a special machined aluminum threaded bottom bracket that threads into itself. Coated FinishThe unique coating formula is a metallic layer that covers the bearing races and makes them 75% harder than steel. Thanks to this, they are highly resistant to corrosion and the coating provides an even lower friction than the standard bearings. Even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible with the coated version. CeramicSpeed coated products are covered by a lifetime warranty. The CeramicSpeed DifferenceCeramicSpeed Standard Bearings last at least three times longer than other bearings. That’s thanks to hardened-steel races and CeramicSpeed Balls that are 100% smoother and 15% harder than other ceramic bottom brackets. CeramicSpeed bearings have a frictional drag of 0.3-0.4 watts per set, which represents an average 75% drag reduction compared to other BBs.
