My ’74 Raleigh Supercourse frame came with a 130mm rear fork spread. I suspect it was cold-formed at one point as these frames originally came with a 126mm spread. I recently purchased an older 27" wheelset that has a 126mm spread. I realize that by inserting spacers between the forks and the hub, I can make up for the 4 mm difference. However, will there be any problems when shifting with the rear derailleur with this odd setup?
