Here's the Sedis/Sachs narrow silver chain installed on my last build:
I was really surprised how well it works on my 6 speed drivetrain as I only used these narrow chains o 7 speeds. I also like very much how the Sedis silver chains are actually more like nickel colored. I prefer its looks over the more silvery and chromey looking chains from other manufacturers. This particular Sedis/Sach chain notes on its box that it is corrosion proof. I bought an identical chain a few years ago for my Vitus Carbone that was surprisingly packaged as a Campagnolo Chain.
