G3 HG-R Driver and Pawls with 1.85mm Spacer

Project 321 G3 HG-R Driver and Pawls with 1.85mm Spacer is a direct-fit freehub driver kit for Project 321 G3 hubs, built for riders who want to service a worn driver or convert a G3 hub to the HG-R interface. By replacing the driver and engagement hardware together, it helps restore consistent pickup and keeps the hub running the way it was intended—without mixing old, worn parts with new components.

• HG-R Driver Interface - Enables compatibility with drivetrains that require an HG-R-style driver on Project 321 G3 hubs
• Included Pawls - Replaces key engagement parts in the same service to help maintain crisp, reliable engagement feel
• 1.85mm Spacer Included - Provides the correct spacing for the intended driver setup, simplifying installation and reducing guesswork
• G3-Specific Fit - Designed specifically as a Project 321 G3 hub driver replacement/conversion part for straightforward compatibility
