Mount Arms

A mount arm is used to connect a Garmin or Magene to one of our mount bases.  Each mount arm is designed for a specific configuration and device.  Some may extend the device further back for increased saddle bag clearance, whereas others may be designed for rougher riding to prevent movement on rough surfaces or bumpy roads. GoPro and similar devices connect directly to the mount base, but you may want add a separate safety tether with those devices.
