I’ve completed the front triangle on my first frame and I’m about to do the stays and the dropouts. I’m using Columbus horizontal dropouts and I’m wondering about the placement of the drive side dropout. My concern is about chain rub in the highest gear. I saw a Chapman video on Instagram where his just puts it off center of the stay favoring the inside to compensate.
I’ve looked at the steel frames I own and one (Serotta) looks like it was machined or filed down with the dropout still centered. Another (nishiki Olympic) the dropout again looks centered and both the chain and seat stays look almost flattened. I looked through my copy of the patereck manual and he just centered the dropout. Probably because it was all 6 speed back then and lots more room. Thanks in advance for your help.
