Find your genuine Shimano bottom bracket replacement parts at Escapa. The Shimano 86.5mm SM-BB71 Press-Fit Road Bottom Bracket is designed for press-fit installation of a Hollowtech II-compatible crank on a road bike frame with an 86.5mm bottom bracket shell width. As is standard with Hollowtech II, the bearings have a 24 mm diameter, providing the best combination of rotational efficiency, stiffness, load capacity, sealing performance, and weight—even with press-fit bearings.
The SM-BB71-41B bottom brackets are recommended for older 10-speed road and cyclocross cranksets
