I asked a similar question in the Cannondale form section, I am looking at the same two bikes. I have had a couple of responses, but would like to hear more about this, hope you get some answers.shotojs78 said:Hi, I know the difference between caad 9 and system six. But I can buy a used caad 9 (400 miles) = 500$ frame and fork
or a system six (1200 miles) 850$... just frame and fork... and I would like to know if I can see a big difference between these frames... the difference is 350$$, it's not huge.. but with 350$ I could buy a better wheelset..... ?? what do you think
BTW I am after a 60cm System Six or CAAD 9 frame set, PM me if you can help.:thumbsup:
cheers
