I bought and installed a cheap rear rack for my commuter a while ago. It works fine, no complaints there, but it's caddywampus lean upsets my commuter chi. When I first installed it I used both of the threaded holes near the dropouts, this seemed logical to me, but it is my first rack. The result was so off-kilter it had to be wrong. I ended up using one of the threaded holes and then on the other side I put a longer screw (from the inside out) through one of the holes for the disc brake mount and tightened it with a locknut. It's better, and like I said functional, but still crooked. Am I dumb? Is my rack dumb? Is the frame dumb?
