7 speed uniglide to 8 speed hyperglide
I have a 7 speed Shimano Sante group on my 1988 Miyata Twelve Hundred. Replacement cassettes are insanely expensive. Wondering whether spacing between 7 and 8 speed cogs is the same. If so, I would switch out the 7 speed uniglide hub for an 8 speed hyperglide hub, slap on an 8 speed cassette and use the lower limit screw on the RD to avoid the smallest cog. Has anyone done this?
