CeramicSpeed T47/86 Inboard Bottom Bracket for Shimano

The CeramicSpeed T47/86 Inboard Bottom Bracket for Shimano is made for T47 85.5 and 86 mm road shells and works with Shimano road cranksets. T47 bottom brackets use the oversized interface of PF30 and EVO386, but with the benefit of a threaded design.

The CeramicSpeed Difference

CeramicSpeed 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.

Coated Finish Option

The 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. In addition, the coating provides an even lower friction than the standard bearings. Even if you contaminate the bearings 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.
