BB30 Shimano/SRAM Ceramic Bottom Bracket

Use "Product Finder" to find the compatible bottom bracket

Cannondale introduced the BB30 standard in 2006. It is aiming to increase the pedalling efficiency by decreasing the distance between the pedals - decreased Q-factor.

BB30’s bottom bracket bearings fit inside of the frame bottom bracket shell directly requires the shell ID 42mm and the width 68mm.

With a need to install a Shimano 24mm/SRAM GXP 22-24mm spindle crankset into the BB30 frame, it will require this BB42 (BB30-24) ceramic bottom bracket for the conversion.
