Well not really a disaster, but pretty stressful. I got my chain tension fixed up and now I have noticed some chain rub on the bottom of my deraillure. On the side not facing the tire, the peice of metal that supports the bottom pulley wheel, on the very tip. This happens when I'm running the big chainring (53) and on any of the 3 biggest cogs in the back. I called a cycling shop but the guy didn't really help me too much. He said I may need it adjusted, well how do you adjust, what tools do you use?
thank you
a very frustrated ameture

First make sure the two limiter screws on the rear end of the derailer is set correctly. Then adjust the "thumb knob" on the back of the derailer where the cable goes into the derailer by adjusting in very small turn "clicks" and then shift and derailer and pedal the bike and keep on turning the knob and then pedaling until you notice the shifting is precise and is not rubbing, making unusual noise, or not working as it should be.

You may also need to get a bike maintenance book as I learned this derailer adjustment thing from a book. \

I figure if the derailer and chain are still making noise after all efforts, you may need to get a LBS to adjust it for you or the part of the bike where the derailer hangs or the derailer itself may be damaged or bent.
