On the plus side, it's a better BB, and I was going to do something like that anyway. But I should have been a bit less sure I knew what the problem was. Since it was EXACTLY the same creaking noise, I spent more time diagnosing it. It doesn't happen when I'm out of the saddle - AT ALL. It doesn't happen as much when I'm on the saddle working hard, like a seated climb. It happens when I'm pedaling along on the flats, and I can make it better by concentrating on pedaling circles. I thought it might be the bars, but then I tried torquing them up and down, and nothing. My best guess is the seatpost, or rather the seatpost/seat tube interface. So I pulled the post last night, slathered it with the last of the carbon assembly paste from the assembly kit that came with the bike, and carefully torqued it down to the indicated 5 Nm. We'll see. Over the winter, when the bike was on the trainer most of the time, I had lowered the seatpost about 3-4 mm, chasing the elusive Perfect Position, and it's possible I didn't torque the clamp screw enough.

We'll see, and hear, tonight. If that doesn't fix it, I'm not sure what I'll do next.
