It's time to introduce STI shifting to our 1980 Santana tandem, only problem is finding a suitable rear hub for the 140mm OLD spacing.
I'd prefer to avoid cold setting in favor of using a modified hub. I'm leaning towards an older XTR M950 hub with a longer replacement axle. I can't seem to find much info on whether this would work and where to find a 150mm replacement axle thats up for the job. Anyone have experience with this?
