Gee. I can't believe I said SGI and twice!!! I'm at work too much.... Thanks for the informative updates. A lot of people said they had no problems etc with their setup. I know that TONS of people do fine with STI. I wasn't looking for that.
Has anyone actually done it? Or is it just a couple of pros for reasons we cannot seem to actually nail down?
I know about limit screws and setting up. I've had 6 attempts by LBS mechanics... I've changed Chain Rings to Dura Ace etc. I have a Dura Ace setup (although the crank is Specialized Carbon S-Works oversized BB).
I liked the comments about Campy I had no idea they actually run on a different mechanism. Just thought it was a different company producing in essence similar designed stuff. Need to do more research on the Ratcheting you talk about.
