I'm doing my first real climb tomorrow and I noticed my front derailleur rubs on the chain when I'm in the smallest chainring in front (triple) and largest cog in back. I tried adjusting the set screw, without any tension on the cable. The problem is that when I adjust it as far as it goes towards the seat post it still rubs. I can't slacken the cable any more and adjusting the screw no longer moves the derailleur. How can I get it to move in more? Do I have to bend it? Is the bottom bracket spindle too short? Is there anything I can do to move the derailleur in more and eliminate the rubbing? The quicker the advice the better as I'd like to adjust it before early tomorrow morning. Thank you.
