Hmmm, update
after some fiddling, I got this unit shifting pretty smoothly with the origingal derailleur the FD-6600. That is to say, on the stand. There are two distinct clicks going up to the big ring.
And by just pulling the cable, it also shifts up pretty smoothly.
But when I take it out on the road to test it, it again hesitates going to the big ring. I have to really hold it or press the big lever hard to make it ride up. (And I dare not try the cable pulling test out on the road I don't think. It's so cold here that I can barely think)
Why would it shift better on the stand than out on a road test.
(and I can imagine that trying to use a 6500 might not be a good long term solution as it might not respect the designers compatibility vision. But I just wanted to try it to see if there was something about the FD itself)
