I wanted to put this in the rear of a 120 spaced bstone track frame as a fun way to change up the bike when i get tired of having my second bike be fixed (which happens about 10 times a year). I thought the 7s and 8s where closer to 120; maybe 125 or 128 where i would only have to coldset my rear triangle. I have a nexus 3spd thats 120, but id really rather go with a full range of ratios. Anyone know if i can respace the 8 nexus to get it closer to 120ish?( i bet the alfine is way out of my spacing league).
