The G Funk is a two part clamp design that's designed to allow you to fit a Strapdeck in front of or below your bars in order to strap something like a drybag to it for solid-no-wobble-or-shake carrying goodness. Clamps are 32mm (actually 31.8mm) to fit either side of your stem on almost all modern bars.
**NOTE THIS IS FOR THE 2 X CLAMP
