G3 MicroSpline Driver and Pawls with 1.85mm Spacer

The Project 321 G3 MicroSpline Driver and Pawls with 1.85mm spacer is a direct-fit freehub body kit for Project 321 G3 hubs, built for riders running Shimano MicroSpline-compatible cassettes or converting an existing G3 hub to MicroSpline. Including new pawls helps ensure a clean, consistent interface during a driver swap or service, while the included spacer supports correct installation stack-up for the intended hub configuration.

• 1.85mm spacer included - Helps achieve proper fitment during installation for the specified setup
