The FSA BB-9920 Platinum ISIS bottom bracket is a dependable and durable unit designed for use with ISIS Drive splined cranksets. Built with high quality materials and precision engineering, it delivers excellent stiffness and smooth rotation for efficient power transfer.

A forged hollow chromoly steel spindle provides strength while keeping weight low, while the integrated large ball bearing design allows for maximum bearing size and durability. Cold forged aluminium cups ensure a secure BSA threaded fit, and the composite anti creak sleeve helps reduce noise under load.

Improved external seals protect the bearings from water and dirt ingress, making this bottom bracket suitable for regular road or off road use.
