The FSA BB386 EVO Adapters BB8630 Cups are designed for customers working with the BB386EVO family of bottom-bracket standards and crank compatibility. Before ordering, confirm your frame shell width and crank spindle diameter, as BB30, BB386EVO, threaded and 24 mm systems use different arrangements.

The FSA BB386 EVO Adapters BB8630 Cups are a compact solution for adapting bottom-bracket and crankset standards where the frame shell and spindle do not use the same format. They belong to the BB386EVO ecosystem, built around a 30 mm alloy spindle and an 86.5 mm-wide shell arrangement.
The BB386EVO concept combines a wider shell with press-fit bearing cups and was developed to offer broader crankset compatibility than a single frame standard. Adapter arrangements can also reduce a 30 mm bearing interface for 24 mm integrated spindles, making them relevant when fitting compatible crank hardware to an EVO-style frame.
Compatibility is the key consideration here. BB30, press-fit BB30, BB386EVO and threaded 68 mm shells are not interchangeable without the appropriate cups, reducers or spacers. If you are unsure, check your frame’s bottom-bracket shell, crank spindle diameter and crankset model before purchasing; we recommend professional installation where tolerances or press-fit parts are involved.
Best suited to a home mechanic or workshop replacing bottom-bracket cups or resolving a specific BB386EVO crank-and-frame compatibility requirement.
BB386EVO compatibility
Designed around the BB386EVO bottom-bracket family for bikes using this wider shell standard.

Aluminium construction
The published product listing identifies an aluminium body material for a durable, serviceable part.
Black finish
A discreet black finish integrates neatly with most crank and bottom-bracket assemblies.
Check before ordering
Matching the frame shell width, spindle diameter and crankset standard is essential for correct fit.
