I have these and they work great.

They are on sale for $50 right now.
Larry - Do you need side bag supports to keep them out of the wheels without something like the Cyclerack supports? How/Where did you mount them? Have any pics?
I'll round up some pics when I mount them back up.
Basically they are very short and it has never been a problem. I pull the straps very tight and that seems to pull the tops of the bags in while pushing the bottoms out away from the tire. I have a cycle rack and have tossed around the idea of making some bag supports but never have needed it. I forgot to mention that I have a tool tube on one side and that keeps it in place there.
I'll get some pictures asap and post them. I never figured they would go back down to $50 again.
