Im strapped to a 120mm spacing
I would love to build a wheel with those nice tight UG IG cogs.
Im running a 5 speed freewheel, and the ultra 6 just wont work because of dated cog profiles,
I have tried all kinds of chains
the only solution to get 6 or maybe even 7 is casette or try to find a shimano sis 5 speed-which most likely also dos not exist.
