I'm glad you're happy with your hipster black, but I'll stick with Silver for my sprokit and Gold for my chain. As you know I already have Gold nuts.
I'm happy being un-hip, I take the windswept and interesting route..
Last time I bought a Renthal rear they were bronzy by defualt so I sprayed it Silver. Never had a problem with ally rear sprokits, but I did destroy a set at the last weekender. Several hundred sodden wet miles through mud, grit and sheep dip saw to that.
I'm running Ognibene now, which are steel and have hard rubber cushions for the chain which is supposed to make it quieter? Not sure about that, but 5000 miles down the line they still seem good apart from the tsunami of thick black chain grease hanging from the front sprocket cover. I could be accused of over doing the lube after the Yorkshire/Cumbria episode, but I do ride it through the winter.
