Shimano 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 road and cyclocross cranks.
