how does a 9 speed cassette fit on a 7 speed freehub?
was there ever an 8 speed uniglide freehub?
just curious...
Interesting question. The 6402 freehub is UG and HG.
IIRC, the interesting part is Shimano made a Dura Ace UG 8 speed cassette, but the 1st position threaded cog was not compatible with non-Dura Ace UG freehubs. I don’t recall a Shimano 600 UG 8 speed cassette, but they may have offered one.
