Now I am confused with the DA rear derailleur...opencl

Has anyone brought a Dura Ace rear derailleur 7700ss with instructions that state the maximum sprocket is 27t?

I got a DA rear derailleur from performancbike while it was on sale. The instructions say that the max is 26t. I am planning to put in a 12-27. Will this setup OK? I need definite/explicit answers. I appreciate your help. I am currently contemplating on whether to return the derailluer or not to performance... Unforturnately, my bike frame hasn't arrive yet. so i can't try it for now...

The 7700SS will work fine with a 12-27 - I have thousands of miles on my 12-27 cassette this way (as do many of the others who posted replies to your original thread).
The instructions have always said that it was 26t max (I just looked at mine - 3 years old). The Shimano web site on the other hand says 27t max. Either the web site or the instructions are a misprint. Experience seems to show that the instructions are incorrect.
The bottom line is that it WILL work. Keep it, install it, pay attention to the B-screw adjustment (as per instructions) and you will be a OK.

It's just that on performance's catalog, they have the 27t max DA r derailleur, and it has a different catalog number than the one they have online, which is the 26t max one.
