thanks, vixtor. i've also read that the cranks are decent on my kilo, it's not like i have a problem with it. i'm just really picky about chain tension and lube, just as i'm sure you all are, so i was curious if a better crank set would be noticeable upgrade. i didn't even think about just getting a chain ring first, thanks for the advice. messenger's are 130 bcd, would they fit my truvativ?
