FSA BB30 to BSA adapter

The FSA BB30 → BSA adapter allows cranks with a threaded BSA (1.37” × 24 TPI) bottom bracket to be fitted in frames with a BB30 press-fit system.

• Converts a BB30 frame to the BSA threaded standard – simple and safe installation with no gluing or frame modification.

• Compatible with FSA MegaExo, Shimano Hollowtech II, SRAM GXP and other cranks.

• CNC-machined aluminium – high precision, stiffness and low weight.

• Sealed construction – protection against water, dust and dirt.

• Can be removed again without damaging the frame.

• Black anodised finish with a laser-engraved FSA logo.
