In all liklihood I will wait for some time yet. I just have this awesome shiny new toy in front of me and I don't know how to learn about the pieces. I just learned from the SRAM site that my rear derailers are actually designed for mountain bikes, but I don't know how that influences the behavior of my bike. Also, all manufacturers say that their products are stellar, so obviously the SRAM site isn't where I'll find out how they measure up to common alternatives. I'm just curious, this is part of my process, to learn about the pieces.
