The Garmin mount arm allows you to mount any accessory that uses a standard Garmin Quarter Turn connection. Typical use is for Garmin Varia radar lights, but others use the mount to hold cycling computers for cyclocross races.
This Garmin arm will fit our Universal Mount System (UMS).
The mount arm comes complete with all necessary hardware; however, it needs a Universal Mount System.
Version 5 improves the reinforced back with a slightly thicker central channel with a better aerodynamic integration. It is made from tough Nylon plastic, and uses a glass-filled nylon insert for the connection to the Garmin unit.
