If I have this right, the cassette may be cheaper, but only if you are staying with the same # of cogs, if not, I'm going to have to change the shifters and the chain also, and then the chainring would be cheaper to change. The other option I was considering was going to the newer standard 50/34 and leaving the cassette, but not sure about a few things - Do you have to change the crank arms also, or can you just replace the rings (everywhere I've seen them advertised as a set, not sure if they come seperately). Anything that would make me change the bottom bracket?
