Description  

Shimano’s SM-BB92-41B bottom bracket provides a seamless connection between your HollowTech crankset and frames designed with a BB92 press-fit shell.

Its design balances durability and ease of installation while protecting against water and debris intrusion.

This bottom bracket performs reliably across road cycling scenarios, from long-distance rides to fast-paced group sessions. Its wider 86.5 mm shell accommodates modern frame geometries, allowing more space for innovative seat tube and rear suspension designs. Sealed cartridge bearings and dust shields maintain smooth rotation while minimising maintenance, even under challenging conditions. The composite cups reduce the risk of frame damage and prevent creaks, making it suitable for advanced riders seeking consistent, quiet performance.
