Don,

I would ask, why do you want to? If you desire to run a contemporary drive train, find a frame which was designed to accommodate them.

This is sort of like the "Apples & Oranges" thing. It can be done, but seems rather like a waste of effort (IMO). The modern drive systems have 130 mm (road) spaced rear hubs, and (good) frames which are 120 mm spaced should not be cold set to that distance. I have serious reservations about going from 120 mm to 126 mm!!

Buy another frame and keep the Original (120 mm) - Original! Oh, and if you do want to buy a 130 mm spaced frame, I have this Colnago which has been gathering dust.....................
