    FSA Crankset / Chainrings for Dura Ace

    Hey all,

    Searched around but I didn't find the answer I was looking for.

    I have a BB30 compact (110mm, 50/34) FSA Gossamer crankset but it's not entirely compatible with the Dura Ace gruppo. Evidently FSA offers inner and outer chainrings with a modified profile to optimize the DA 7900 drive although my crankset will "work".

    Rather than purchase an entire crankset (such as the SL-K Light) is it possible to just purchase the 110mm 50 and 34t chainrings evidently used on the SL-K and place them on the Gossamer crank?

    From all of my research online I can't determine if this would work.

    Basically just trying to run a DA 7900 group on a BB30 FSA Gossamer crank at this point.

    Thanks for any insight!

    What is wrong with your front shifting at the moment? Maybe a little adjustment to the derailleur or the cable will improve things and mean that you don't need new chainrings. If you do decide to go for new rings, there is probably no need to change the inner ring because that is pretty simplistic and doesn't do much work to help shifting, the big ring is the important one.
