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.
The short version moves the light up higher and further away from the saddle leaving more room for larger saddlebags. It is also intended for UMS™ bike rack mounts.
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 3 is thicker with a reinforced back to withstand high frequency impacts from off-road or other rough riding. The new arms are now made from impact resistant Nylon plastic.
