OK, so I've almost completely got my SS built up, but I'm having some chain issues. I'm running 32-18, on a soul cycles frame with horizontal dropouts. I'm using an sram 8 spd chain, and my problem is that I either have no slack at all, or (with just 1 more link) I have too much slack. And even if I try to slide the wheel back on the dropouts, the chain can still pull it out of alignment. Anybody know how I can remedy this?
