I currently own a stock Specialized Roubaix with a 105 group. I have the opportunity to aquire a Dura-Ace Triple Crankset (FC 7703) and a 9 speed Dura-Ace cassette (12-27). Will these new parts work with my 105 group? I'm planning on buying a new wheel set for racing only and will likey put the Dura-Ace cassette on that.
Thanks for any help you can offer,
Bruce

Yeah, it works, assuming your 105 is 9 speed and you have a triple already. Make sure the chain is long enough for the 27 if your other casette has a smaller big cog. What's the pont of a triple on a racing bike. Unless everything is a tough mountain stage?

Thanks for the quick reply. I'm going with a triple because it's what's been offered to me and it's whats currently on my bike.
Living in Chicago, I have VERY little need for anything but 52-17 gearing for normal riding! 😉
Thanks again,
Bruce
