The style and strength of the bags are grear
However for the duo i had to snap the 2 u clips on the underside off in order to stretch the panniers over the racks and secure the underside to frame. The u clips don’t work on the larger frame so I’ll guess these are stock bags meant for multiple models.
Comes with a rain cover as well. Sorted properly it hold everything.. helmet and clothing gear on one side, tools, accessories, food i. Others. And has 2 rear storage zips as well to hold drinks and zip ties
