He suggested that I purchase the IRD deraileur designed for use in braze installations with a compact crank,
Sometimes with a barzeon, it's not possible to lower the FD enough to worjk with a 50 ring,but that's unusual,and often can be fixed with a dremel tool to the hanger. I don't know that it's a given that the IRD in itself cures this problem.If he didn 't actually try the ultega in your application, I suspect he was just blowing smoke.
