MICHE bottom bracket T47 RD EC 24/30 ceramic for Hollowtech II / 30 mm crankshafts
If the frame is the skeleton of the bike, then the bottom bracket is its beating heart. It absorbs the power generated by the rider, distributes it efficiently and transforms it into propulsion. Miche bottom brackets have been developed to reduce friction to a minimum, optimize power transmission and ensure a long service life. The result: consistent performance and maximum reliability over a long period of time.
The Miche T47 EC Race Division is manufactured with high-quality 7075-T6 aluminum bearing shells. High-end ceramic bearings from CeramicSpeed ensure silky smooth running. The SpeedBalls used by CeramicSpeed are 15% harder than those of the competition and can absorb considerably more force. They also have an incredibly smooth surface, thereby reducing rolling resistance to a minimum. Thanks to the two different sets of dust caps supplied, the bottom bracket is suitable for Hollowtech II crankshafts with a diameter of 24 millimetres as well as for cranks with a shaft diameter of 30 millimetres.
