The Shimano SM-BB72-41B is a press-fit bottom bracket for frames with an 86.5 mm shell width and 41 mm internal diameter. It is designed for Shimano HOLLOWTECH II cranksets using a 24 mm spindle, making it a practical replacement for compatible road and gravel builds.
Inside, widely spaced bearings support the bottom-bracket axle to help maintain stable pedalling and efficient power transfer. Shimano bearings and seals provide the protection you want from a daily-use component, while the compact design keeps the claimed weight to 69 g.
Before ordering, check your frame’s bottom-bracket standard and shell dimensions rather than relying only on the bike’s groupset. The SM-BB72-41B is listed for a broad range of Shimano Ultegra, 105, Tiagra and Sora HOLLOWTECH II cranksets, as well as selected GRX and other 24 mm Shimano cranksets.
