Bike Rack installation problem

[Catrin]

A strip cut from an old inner tube makes a nice non-marring shim. I would think if it's not thick enough you could make a longer strip and wrap it around once, but I wouldn't wrap it more than once since it could make the rack unstable.

Good thought Oakleaf and one I hadn't considered. I don't have any "old" inner tubes, but I do have several extra and they aren't that expensive. I hope to FINALLY try my commuting route this Saturday - depending on what the rain does...
