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.
