I did have a pretty spectacular drop while having on of these Pro City bags on my bike and it was very difficult to get it off. Once I got it off, and cleaned out the spring loaded mechanism it worked perfectly thereafter. So yes it could be a problem, but in my express far, it will be least of your problems that day!Valid point, but I've been using SW-MOTECH tank bags for over a decade (first gen, EVO, Pro) on all my bikes and this never happened to me. That would be the last thing to break on the bike I'd worry about.
