My son's bike's rear derailleur has, since new, been swinging up and hitting the chainstay. I've finally decided to do something about it (too late to go back to LBS) as he's using it more now. I had fixed rubber pads to the contact point but these were trashed by the action after a short time. I've looked on t'internet but couldn't find any real solutions.
Has anyone else on here experienced this problem.
