Technical Specifications

• Frame Shell Width: 68mm (Standard Road)
• Crankset Standard: BB386EVO (30mm spindle with extended length)
• Spindle Diameter: 30mm

Compatibility Warning

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.
