Evening,

I am working on my Motobecane GR project, and am stumped. I spread the rear from 120 MM to accommodate a 126 MM Campy SR hub w a 7 speed Regina freewheel. Things were working OK. Then, I swapped out the Regina freewheel with a Sachs 7 speed to get some easier gearing for my hilly area. The Sachs seems to be a bit wider than the Regina, and when I am in the smallest gear, the chain rubs against the seat stay, right where it connects to the dropout. So, I tried moving the hub cones over a bit, to shift everything towards the other side, and make room for the wider freewheel. Still rubs, and the axle length does not allow me to move it over any more. The axle is 134 MM. In case it matters, I have a Campy SR RD. So, I'm out of ideas and need some help. Thanks
