Shimano Pressfit SM-BB72-41B Bottom Bracket
Shimano Pressfit SM-BB72-41B Bottom Bracket Info
The Shimano Pressfit SM-BB72-41B Bottom Bracket is a press-fit shell bottom bracket designed for Shimano road cranksets running 24mm spindles. It's built to Shimano's established tolerances, delivering a stable, quiet interface between your crankset and frame — without the weight penalty of external cup designs.
The SM-BB72-41B is intended for frames with a 41mm press-fit shell, making it a direct-fit solution for road bikes built to that standard. As with most Shimano drivetrain components, it's engineered to work seamlessly within the Shimano ecosystem, so you're not chasing compatibility compromises when pairing it with Dura-Ace, Ultegra, or 105 cranks.
