My LBS is telling me that there are no issues with just the crank set but i've read on other forums that you have to have a 7900 chain which is not compatible with the 7800 Rear d. I can't seem to get a straight answer -

as long as it's the same size and its teeth match up it should work. 130 bcd and 53 teeth 9 or 10 speed should interchange. as far as i can tell the only thing different from the 7800 and 7900 chains is the weight and the directional of the 7900. oh, and the crappy quick link.
