Garmin Replacement Disk (For CM03/04 Mounts)

What Our Gearhead® Experts Are Saying:

"I’ve replaced a few of these after hard knocks, and that’s the point. It’s better to swap a low-cost disc than risk damaging the tabs on a head unit. The fit is tight in the mount, and installation only takes a few minutes with basic tools."

When we rely on real-time data for pacing, navigation, and performance tracking, a secure mount interface is non-negotiable. The Garmin Edge Aero Replacement Disc is engineered to restore the integrity of a worn or damaged quarter-turn connection, ensuring our head unit stays firmly in place over rough pavement and high-speed descents.

This precision-molded disc interfaces directly with compatible aero-style mounts, maintaining a consistent, tight engagement with the quarter-turn system. Its breakaway design acts as a protective measure in crashes, sacrificing the disc before the more costly computer tabs are compromised. Installation is straightforward, allowing us to quickly refresh an existing mount or convert setups when needed.
