Another couple questions(maybe even dumb ones at that lol).
Is there anything I would need to be aware of(other than BB size & length) if I decided to switch out the whole BB/crankset from what I have? I have the older square taper but almost everything now seems to be ISIS. I don't care about having top of the line stuff on a beater but having to scrounge around for used parts isn't exactly fun in my book.
I can use a narrower(or wider) BB to help adjust my chain line without screwing anything up(assuming nothing rubs), correct?
Do the SS specific cranksets move the chainring in so that your sprocket isn't out so far? If not what purpose do they actually serve? Is it just cosmetic?
It seems like you'd want the chainring as close as possible to the frame so the sprocket would be closer to the body of the hub instead of out near the end of the axle. I'm using an old Shimano 7spd hub with just a single sprocket and pvc to space it properly for a straight chainline. With my current crankset(have no idea what they are but the outer chain ring bolts to the middle ring not the crank arm spider) using the middle ring my sprocket is way out by the frame to get a straight chainline.
After typing that last bit up I had a thought, SS or fixed hubs must be wider than a cassette hub.
