SHIMANO BOTTOM Bracket SM-BB71-41B HOLLOWTECH II PRESSFIT 41 X 86.5 MM

Shimano SM-BB71-41B is a Pressfit bottom bracket for mounting Hollowtech II compatible cranksets in a road frame with an 86.5mm wide bottom bracket. As usual with Hollowtech II, the bearings have a diameter of 24 mm, because it is the best combination of rotational efficiency, rigidity, load capacity, sealing and weight, also for housings with pressure. SM-BB71-41B bottom brackets are recommended for older generation 10-speed road and cyclocross cranksets.
