I just leave the clamp on the bar all year long. Here's what that part of the clamp looks like.

It's fairly low profile and could easily be mounted upside down.
Cheers; my bag actually mounts in towards the rider:

I like the look of those cam-locks better than the threading my current light mount has. It's minor details, though. Is that bar mount one of their products? Didn't spot it on their site - clever, though (I assume this causes no issue with getting the headset tight?).
