I found on the 'net some interesting (in a nerdy, arithmetic sort of way) info on shifter cable pull, derailer actuation ratios, and cog spacing. Naturally, I loaded it all into a spreadsheet for fun. After looking at many different permutations, I came upon one that seemed fairly useful. If you have a nice SunTour rear derailer and you'd really like to use it with more modern, indexed shifting, it works perfectly with a Shimano 9-speed shifter and a Shimano/SRAM 8-speed cassette. I just tried it out on my Riv ATB and, sure enough, the spacing is exactly right. Since I'm a big fan of Shimano 9-speed bar-end shifters, and my ATB has a nice XC Pro rear derailer, it's a very happy coincidence for me.
