Profile Racing Retro American Bottom Bracket Cups

No, these cups are sold as a pair without bearings. This allows you to choose the specific bearing type and quality that best matches your riding style and drivetrain setup.

No, these are specifically designed for standard American bottom bracket shells. They will not fit frames that use Mid or Spanish bottom bracket standards.

Because they are a classic design, they are straightforward to install and maintain. Ensure your frame's bottom bracket shell is clean and properly greased before pressing the cups in to prevent creaking and ensure a secure fit.

While they are designed with an authentic vintage aesthetic, they are intended for use with frames that utilize the American bottom bracket standard. If your modern frame uses a different standard, these will not be compatible.

These cups offer an authentic, clean look for restoration projects or custom builds that require the classic American standard. They provide the flexibility to select your own bearings, which is ideal if you have specific preferences for bearing performance or serviceability.
