Shimano Ultegra SM-BBR60 Bottom Bracket
What Is the Shimano Ultegra SM-BBR60 Bottom Bracket and What Does It Fit?
The SM-BBR60 is Shimano's threaded English BSA bottom bracket for Hollowtech II cranksets, designed to pair with the SM-BB press-fit adapter system used on Ultegra FC-R8000, FC-R8100, 105 FC-R7000, and other Hollowtech II cranks that require a threaded English shell. The SM-BBR60 uses an integrated cup-and-bearing threaded design that installs directly into standard 68mm English-threaded bottom bracket shells without any additional press-fit hardware. The bearing assemblies are housed in the cups themselves and preloaded against the shell face, providing a solid, rattle-free interface that is straightforward to service and replace compared to press-fit BB systems. This threaded design is favored by many mechanics and riders for its ease of installation, predictable torque spec, and field serviceability.
The SM-BBR60 is compatible with Shimano Hollowtech II road cranksets including the current FC-R8100 12-speed Ultegra series, the FC-R8000 11-speed series, and 105-tier Hollowtech II cranks. It fits standard 68mm English BSA threaded bottom bracket shells, which are the most common thread standard on road frames. For frames with 70mm Italian-threaded shells or press-fit BB86 or BB92 shells, different bottom bracket solutions are required. The SM-BBR60 is the standard recommended pairing for Shimano Hollowtech II cranks on threaded English frames, offering reliable performance and simple installation with a bottom bracket tool.
