A mount from CaneCreek that comes with a Garmin and Wahoo adapter

With 4 front and back mounting directions and multiple angle adjustments, you can adjust your setup for any size GPS computer. This also means that you can adjust it very precisely to how it should be on the side

The holder can also be mounted one bolt at a time, so you don't have to worry about your handlebar moving and needing to be readjusted.

Made of aluminum and black stainless steel bolts.
