My wife's bike has 7 speed RSX, and it's getting RSX disease. I got it to start shifting a little better with a big does of WD-40, but I don't think it's going to last for much longer.
I've heard that 7-speed sora shifters will work as direct replacements. What other options do I have? I'd be willing to consider an 8 or 9 speed upgrade at the same time.
