I have an Ultegra 8 speed cassette (and hub) on my rear wheel. That means I could use 8 speed ergopower with hubbub cable arrangement and then shift through 7 cogs on my 8 speed cassette? Rear derailer is 6208 Shimano (600 series).
Okay - so the ergopower has 8 clicks right? In this case I would be using only 7, and for instance - limit the shifter to use the biggest cog until the second smallest one. Why couldn't be possible to use the extra 8th click on the ergopower to shift to 8th cog on my shimano cassette? Since 7/8 have the same spacing/width...

No, Shimano 7-speed is 5.00, Campagnolo 8-speed is 5.00, Shimano 8-speed is 4.80, just as the chart shows (twice I might add). There's no confusion. You can use a Campagnolo 8-speed shifter with Shimano 7-speed because they're both at 5.00 spacing. Don't know how to make it more clear...
