Description
Shimano SM-BBR60 BSA 68 mm bottom bracket
The Shimano SM-BBR60 is a high-quality BSA-threaded Hollowtech II bottom bracket for Shimano road, gravel, cyclocross, and fitness cranksets. It is intended for 68 mm wide bottom bracket shells with English BSA threading and Shimano Hollowtech II cranks with a 24 mm axle.
The SM-BBR60 offers a lightweight, low-friction, and reliable bottom bracket solution for bikes using, for example, Shimano 105, Ultegra, GRX, or other compatible 24 mm Hollowtech II cranks. External bearing cups support the crank spindle effectively and help keep the drivetrain stiff, precise, and smooth-rolling.
Improved sealing helps protect the bearings from dirt and moisture, making the bottom bracket a good choice for regular road, gravel, and commuting use. The SM-BBR60 is a practical spare part for replacing a worn or creaky bottom bracket, as well as for new crank installations where the frame uses a BSA-threaded 68 mm bottom bracket.
Shimano SM-BBR60 - technical specifications and compatibility
The Shimano SM-BBR60 is a Hollowtech II bottom bracket where the bearings are located in external bearing cups outside the frame. The design is intended for Shimano's 24 mm crank axles and offers a good combination of weight, stiffness, and serviceability.
This BSA version fits a 68 mm wide English-threaded bottom bracket shell. It is a bottom bracket specifically intended for road and gravel use, so it is not the primary choice for Shimano MTB cranksets, which generally use MTB-specific bottom bracket models and different spacer configurations. Proper compatibility should be checked against the frame's bottom bracket standard and crankset model before installation.
