With the weight of the rack (and bags) and the bumpy roads, they 'shimmy' down until they hit the dropouts, and scratch up the frame a lot. This is why I was hoping for a frame with built-in threaded braze-ons.
That's interesting mate. I use P-clamps with a bit of inner tube underneath without a problem and I would have though the coating on those clamps would have done as well. Maybe try a bit of inner tube. You're right though, proper threaded mounts on the frame are the best way ... but you have to pay for 'extras' like that.
