The rub that I was talking about is the rear derailleur when you are in your 32t and your small chainring up front. You may indeed have a Shimano "gs" road derailleur, so you wouldn't have any rub where the derailleur hits the 32t. In terms of your front derailleur rubbing on your chain, that is simply because the derailleur limit screw is abit too tight. Whether you had a 32t on anything else as your low end on your cassette, that won't have any affect on chain rub unless the limit screw isn't set up correctly. The other factor here can also be the chainline of your bike. You might have your LBS check this the next time that you have a new chain replaced.
At any rate, thanks for the answers!![]()
