This Tange Seiki BB30 Bottom Bracket Adapter is a high-quality conversion sleeve designed for riders looking to install a traditional threaded bottom bracket into a modern BB30 press-fit frame. Specifically engineered for 68mm shells (typically found on road bikes) with a 42mm internal diameter, this adapter provides a rock-solid, threaded foundation for your drivetrain.
Key Features
-
Standard Conversion: Converts a 42mm BB30 press-fit shell into a standard BSA (English) threaded 1.37" x 24tpi interface.
-
Precision Engineering: CNC-machined to exacting Japanese standards, ensuring a tight, high-tolerance fit that minimizes the risk of creaking.
-
Versatile Compatibility: Ideal for road bike frames with a 68mm shell width, allowing you to use external cup bottom brackets or traditional square taper units.
-
Durable Finish: Finished in a sleek Anodized Black for superior corrosion resistance and a clean look that matches any frame.
-
Stable Interface: Provides a permanent or semi-permanent threaded solution, offering better alignment and reliability than "thin" spacer-style adapters.
