Shimano 8 Speed Indexing: Will This Work?
I cross posted this in the C&V sub forum, but I suppose this question really belongs here.
I'm curious if this will index. I'm going to install the Shimano 8sp bar end shifters (thanks, Brock!) regardless because if it doesn't index to my satisfaction I'll just use the friction setting. But here's what I have.
The spacing on a 6sp freewheel is something like 5.5mm and is 4.8mm on an 8sp, but all that is related to the pull of the shifter itself, correct?

- Shimano 8sp bar end shifters
- Shimano 8sp HG cassette
- Shimano 130mm freehub
- Shimano RD-MT60 long cage deraileur (ca. 1988; meant to index with 6sp shifters)

Right, and the exceptions in regard to a different cable pull ratio of Shimano rear derailleurs from the indexing era are eight speed and earlier Dura Ace and the brand new Dyna Sys "10 speed" mountain bike stuff. All other index-compatilbe Shimano rear derailleurs use the same cable pull ratio.

So, well biked, are you saying that the RD-MT60's pull ratio won't jive with the 8sp shifters?
