yes i agree. You need to adjust the derailer. Also, especially going up to 3, you need to click in into the top gear, but also push it that extra bit furthur for it to change. But it would all be in the adjustment of the derailer cable and position. It is also normail for the chain to rub against the derailer. It depends on what gear you are on your back set. (1-7or8) if it is in 1 to 1, the chain will be on an angle, and will rub on the derailer. If the chain is straight e.g. 2 to 4 (prefered gear), then it should run smoothly, and not rub. I have also experienced this problem, and when to my LBS, that was what they told me. Hope this Helps
