Shimano bottom bracket SM BB 72 41B - Press Fit and Hollowtech II

 

Shimano SM-BB72-41B 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-BB72-41B bottom brackets are recommended for road and cyclocross cranks.

 

Technology:

Hollowtech II

Shimano Hollowtech II is a crank bottom bracket system designed to achieve an ideal ratio of stiffness, weight and rotational efficiency. It is based on an integration of the bottom bracket and the right crank arm and works with a 24mm axle or bearing diameter, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside so that the load is better distributed. High-quality precision seals ensure a long service life.
