Granted, seat post-mounted lights would then be sideways, so possibly not ideal. I have a topeak MTX fold-up pannier bag that's 9"-10" wide and I was thinking a cross bar back there shouldn't be wider than say 12" to reduce the risk of catching it on anything. I think my rear rack is aluminum, so not sure I'd want to try welding anything on there. If it was steel, maybe. I was even thinking I could rig something with springs so that if anything does catch the end it would just swing out then spring back. I'd like to hear your thoughts and whether or not anyone's tried this? Or perhaps this should be moved to another thread?
