Campagnolo question
Okay, a question for the Campy braintrust. I have two Campy Chorus 11 rear derailleurs, one has an "A" on the inside arm of the parallelogram, the other doesn't. Here's a pic of the A. And if it makes it somehow shifter specific, how do I tell which set of ergos go with each derailler as I have two sets of those too. Thanks in advance.
