Rob's reply: Ok.
Are there any special problems that I'll have in building up this hub shell, designed for 124 spacing but now with 120 spacing?
Shell is the same
Rob's reply: Actually, they aren't. The flange to flange difference between this campy hub (dated 1965 by the lock nut date) and a somewhat newer (mid 70s) campy high flange is distinct and we would have to defenestrate the notion I think many of us hold closely that Campy paid attention to the details. The flange to flange difference is what first led me to think I might be able to fit an ultra 6 on the newer hub even with 120 spacing. The wheel on the Cinelli right now appears to have very little dish to it at all. Something I chalked up to the wider flange to flange dimension.
Will using a shell with narrower flange to flange dimensions allow me to get an ultra-6 freewheel on there?
Is it true that the NR rear has a capacity of 26 teeth?
You can use an ultra 6 on a 120 hub. That's the reason they exist. And the short answer to the RD question is yes but with some tweeking you can use a 28.
Great. I've also heard from some that in some cases you can even go larger than 28. The current chain ring combo is 47/50. Again, to save wear on the original parts (the crank set is in wonderful condition) I might use a different crank set when I ride the hills around here, which is about 97% of the rides I do that aren't commuting to work.
