Precision-engineered 46mm inside diameter cup spacers designed to fit between your bottom bracket cup and frame.
Machined from durable 6061 aluminium and finished with black anodising for corrosion resistance and a clean aesthetic. These versatile spacers accommodate various bottom bracket configurations and frame requirements, making them essential for custom builds, repairs, and adjustments. Whether you're fine-tuning bearing preload, adjusting cup positioning, or working with non-standard frame specifications, these spacers deliver the precision fit you need. Pack includes multiple spacers to cover different setup scenarios. A reliable solution for mechanics and enthusiasts who demand accuracy in their drivetrain assembly.
Note
- When used with a Wheels Manufacturing GXP compatible bottom bracket, adding cup spacers between the non-drive side cup and the frame will move the chainrings on a GXP crank closer to the frame (reducing the chainline).
- For Specialized road frames with the 61mm wide Carbon OSBB shell, you would place 3.5mm of spacers between each cup to effectively widen the BB shell to 68mm when used with non-Specialized cranks. One bag will properly space one 61mm wide Specialized OSBB shell to 68mm.
