Replace Ultegra 6603 chainring with 6703.
Excuse me if this has been answered before, but I have searched and not found an answer. Can I replace an Ultegra 6603 chainring with a 6703? Specifically, the 39 tooth middle ring, but in general, any of the rings. I don't see any reason not to, but am I overlooking something? Thanks

No, as I gather from the description on this site: http://www.speedgoat.com/Catalog.aspx/Browse?Prod=19321
"6703, triple version uses a proprietary middle chainring that doubles as interface for small/inner chainring mounting"
