However, if I measure at the seat stays, my drive side stay is about 2mm closer than the non-drive side. Brake lines up fine, and everything looks good except for when I put a ruler to it. Could this be due to how the frame was built? Or could it be from my alignment even though it string-tests fine? The frame is a Tenax Schwinn if that matters.
