Built specifically forthe Big Handlebar Bag (but works with Route Werks Handlebar Bag too)
In order to safely use the Big Handlebar Bag on your bike, you need to have 200mm of clearance from the top of your handlebar to the highest point of your front wheel
Dont meet that criteria but still have a measurement from 165 to 199mm? The 31.8mm High Mount is a must-have
