Nah I already checked. It's an older Schwinn passage touring bike and the posts are set too narrow to allow for the 4mm I'd need for 700c (with modern tektro 720 brakes anyway). $80 is a bit too expensive for me. Seeing that the entire bike cost me $375, if I had decided to do this I certainly would have repainted it myself.

Given the cost I guess it was a pretty drastic idea for a solution. Local shop generally sells vintage 531 framesets for $100.

Just annoyed to have broken a spoke whilst unloaded on a 40 spoke touring wheel (I weigh maybe 170lbs).
