Thanks again guys, I have tried to repair the rear wheel using wheel tape (it origionally had a plastic lining which made it really easy to spot the bad spots), but the tire still went flat again. I think it could be the patch on the tube because of the repair I did, and because they are very old patches from the late 90's. As for the front derailleur whenever I go into 1, 1 it makes that metal on metal sound because it hits the chain. The hub is Campagnolo sooo... I do not think it's had a triple-to-double, but it might have had a BB replaced since the bike was origionally shimano, but was converted to Campagnolo.
