Wheels Manufacturing PF30 Adapter for Shimano

This adapter is designed specifically for frames with BB30 or Pressfit30 (PF30) bottom bracket shells. It allows you to install cranks with a 24mm spindle, such as those from Shimano, into these larger shell standards.

Bottom bracket shell widths and crank spindle lengths can vary slightly between manufacturers and models. The 14-piece spacer assortment is included to ensure you can fine-tune the fit, eliminating any side-to-side play for a secure and smooth installation.

Yes, Delrin is an engineering-grade thermoplastic known for its high stiffness, low friction, and excellent wear resistance. It is an ideal material for this application because it provides a precise, quiet fit without the risk of corrosion often associated with metal-on-metal interfaces.

Installation is straightforward and typically does not require specialized press tools. Because these adapters are designed to be a press-fit or slip-fit depending on your specific setup, they can usually be installed by hand or with basic shop tools, though you should always consult your crankset manufacturer's installation guide.

This adapter is optimized for Shimano 24mm cranks. While other cranksets may use a 24mm spindle, compatibility can vary based on the specific spindle length and bearing interface, so we recommend verifying your crankset's spindle specifications before installation.
