    I am buying a FSA carbon pro team issue crankset for my Trek 5500. All drivetrain parts are Dura Ace now. I notice that some people sell the above crankset as campy compatible ISIS drive and as shimano compatible octilink drive. I have an ISIS bottom bracket that I want to install. What I need to know is, is there a difference in chainrings for a campy or shimano drivetrain. I have been told yes and no. I thought that the chainrings are the same on a crankset whether it is ISIS or Octalink. Therefore my Dura Ace chain should run smooth on the chainrings regardless. Is there such a thing as a campy specific chainring and a shimano specific chainring. The specs on the FSA set are 53/39T 150mm spindle 130mm BCD ISIS drive 108mm chainline. Please clarify for me. Is the tooth spacing or shape different for a campy chain as compared to a shimano chain or are they interchangeable???
    Thank you in advance.

    The bolt centres are different between Campy and Shimano, I don't know the bolt centres on FSA
    chainrings, but I'd bet they use the Shimano 130mm. The bottom bracket has no connection wit the
    bolt spacing on the chainrings. Mixing a Campy or other non Shimano crankset/chainring is no
    problem. One of my bikes is set up that way. The front has a Chorus BB, crankset and derailleur.
    The back has Dura-ace der and cassette. I did this to permit me to share wheels amongst all my
    bikes. The rear der and cassette are the only ShamShimano parts on that bike. The rest is all

    Either the '10s' rings of the Campagnolo 10s one or the shimano rings will work fine...

    Your 9s chain will work fine on either ring but you can get a 'shimano' ring crank with ISIS
    BB...good choice, BTW, over the soon to be orphaned octolink..
