And this is just what I did. As mentioned, it doesn’t really change the frame itself. Researching, I’m also thinking this frame originated in perhaps the late 60s or early 70s at the latest, and has probably been through several updates. Filing on the axle did get the wheel to sit straight. I did do a string check on the rear triangle first. It seemed like a lot in the pics to file off the axle, but it was just slightly less than 1.5mm. File install, file install, etc until satisfied. Pretty easy. Also discovered after getting dropout adjuster screws is that the dropout doesn’t sit the same distance back from the BB. The adjuster screws are about 2mm different in depth for the rear wheel to be aligned near the BB. This was probably part of the problem too.

So, progress made while also doing some winter reconditioning on bikes for family members. Fun winter projects. This one is looking to be a half step plus granny. The fork legs are also quite long on this frame requiring long reach brakes. It looks like a Tektro 559 will reach a 700c though, and a 35mm tire will just fit width wise in back. The interest in this frame is the long front center, relaxed head tube angle, and longish chainstays. It sounds kinda floaty considering 35mm tires and the 531 tubing.
