Turns out what I thought might be BB creak was actually saddle squeak. When I was working to eliminate that, I put the bike on the trainer to see where I was relative to KOPS. On the last Madone, I had ended up just slightly forward of that. But either the saddle had moved, or the fitter was on drugs when we did the initial setup on the Giant, as I was well back of that. No wonder I was thinking of raising the bars or moving them back. We'll see how it feels, and as soon as I get 42cm bars, I'll go back and have the fitter take a final look.
