The mount has been extended 13 mm and uses new grip arms for a tighter fit.
Here is an example showing the difference when using the Garmin Varia RTL510 radar light.
The 5th generation mount leaves room for a small saddlebag without requiring an extension.
1) Remove the f'iz:ik name plate and unscrew the stop. 2) Insert the mount and reattach the stop. 3) Mount the desired arm and go.
This mount is our newest f'iz:ik universal mount; however, it is not compatible with the original Shapeways DIY arms, or the Shapeways variant arms offered here.
