You're talking about index shifters, so obviously you have to match the number of speeds to your cassette. The earlier versions are for cantilevers only. Not all of them have those silly indicator windows. Mine are a 7 speed Deore level version that allow you to downshift by either pushing or pulling on the bottom lever. They are on my MB-2 and they work great. I don't know if they made them in silver, but I doubt it. Mine were NOS from eBay and were not expensive. I haven't tried them on north roads, but I suspect that they would be a poor fit. They're designed for flat bars. my bars are bullmoose.
