First off, I really appreciate the insight, you guys have been a big help.

So, SRAM chain (with powerlink, though I'm assuming all SRAM's come with this feature), and pretty much any of the three brand name cassettes (looking at a 12-21). I currently lube my chain about twice a week with a spray lube I got at my LBS. Only question I have left regards cleaning. banerjek, you don't recommend removing chain, so should I just rub it down with a rag? Use some SimpleGreen or something like that?

Again, thanks again guys for all your help.
