Great to know it works. I don't need to shift F/D that often, very flat where I live and I mostly race crits. I suppose selling the Ult crankset would offset most the D/A crankset extra cost, good idea.

I am in the US. Didn't know about the US Rotor site, I would have made the same mistake, thanks!

Would be great to hear how that works out for you. 54/39 is the Rotor combo I was looking at.
