Hey Clay,
I have it and haven't mounted it up yet. Might not even do it. The quality of the bag is very nice. The bag itself is very nice for sure. However, It is very small. It's about the size of a tank bag and won't hold much at all.
Mounting is even worse....there are plastic cam buckles that your supposed to mount/rivet to the outside of the bottom cover on the rack. These buckles stay there all the time even with the bag off.
I think the bag mounting system could have been better designed.
If I use it I'm going to figure out a different way to mount it.......
