With this bottom bracket, you reduce the friction loss that occurs with conventional bottom brackets to around 0.
Yes: ZERO! This is due to the extremely smooth, really round balls (round is not always round, with cheap ball bearings) and the ball race made of hardened steel.
The coated bottom brackets that we prefer also have a metal coating on the inside of the ball race. This makes the bottom bracket even smoother and more durable. So durable that, with proper maintenance, CeramicSpeed offers a lifetime warranty on this bottom bracket.
