The FSA MegaEvo BB-EVO8681 (MPN: 200-3201) is a specialized threaded bottom bracket designed to adapt a modern BB386EVO road crankset with a 30mm spindle into a standard 68mm English-threaded (BSA) frame shell.
This bottom bracket is unique because it forces large 30mm spindle bearings outside of a narrow threaded frame shell. As a result, it requires a dedicated MegaEvo installation tool, such as the FSA MegaEvo Cup Spanner or specialized sockets from Wolf Tooth or Park Tool.
Note: Standard Shimano or SRAM external bottom bracket tools will not fit the wider diameter cup notches.
This product is ideal for cyclists seeking high-performance adaptability for their road bike setups, ensuring durability and precision.
