I know it's not really mechanics per se but does anybody know what I can do about this? I picked up a rack for $10 thinking they all fit universally. It has eyelets on the dropouts for the screws, and I was going to use p-clamps for the seat stays. But it seems that the seat stays are angled too high and it doesn't give the rack enough space to line up properly. I am not sure what to do - I'm running out of options, so maybe I could buy a special rack that mounts on the eyelets, then onto the downtube... if they exist?
