So I have a '70 era Schwinn Varisty. I recently worked on the wheels and tires and reinstalled the wheels. Regarding the back wheel's position in the dropouts here is what I did and have always done but I have a questions. I pulled the wheel on and pulled it back into the dropouts as far as it will go. The drive side stops at the derailer mount and so if I let the wheel find it's center on the frame and roll nicely and evenly then the left side appears to be pretty forward in the dropout.
Is it OK that the left side is not all the way back in the dropout? How far forward to too far? It is well within the dropout and the frame is squarely sitting on the axle. Sorry no picture at this time.
Theories or techniques for mounting and positioning wheels on old steel bikes?
