Thanks,

So my rear dropouts now are spaced at 126mm, and they need to be 130mm for 8-9-10 speed? I'll look into cold-setting the rear. The freehub is longer by 4mm as is the axle, and the wheel has to be dished 2mm to the right?

If I can widen the rear frame spacing to 130mm, and find an 8-9-10 speed rear wheel, then I may try this. The 105 parts are 1055 series from about '93.

If I had the proper spacing and rear wheel, will that wheel take a 8 9 or 10 speed rear cluster? Then match the chain and friction shift?

Thanks again!
