Currently I am using a 9 spd hub with everything else 7 spd. I want to upgrade to 9 spd and I know 9 spd chains are narrower. Will a 9 spd chain be compatible with my crankset? I don't remember what kind of crankset I have (I am at work), but it came stock with my Schwinn Mesa GSX, which is probably a '96?
