Shimano - SM-BB71-41B Bottom Bracket-Pressfit Gloves Accommodates up to 127cm/50" wheelbaseShimano SM BB71 41B is a press fit bottom bracket for the installation of a Hollowtech II compatible crank into a road frame with 86. 5 mm case width. Per usual with Hollowtech II, the bearings have a diameter of 24 mm, as this gives the best combination of rotational efficiency, stiffness, load capacity, tightness and weight even with press fit bearings. SM BB71 41B bottom brackets are recommended for older 10 speed road and cyclocross cranks.
