I've had some chances to take her out to get used to her (series of 15-mile rides), and I got a long ride in over the weekend.

My neck and shoulders don't hurt anymore. Well, my right shoulder started complaining a little around mile 30 or so of a 40-mile ride. The more aggressive position is a lot friendlier to my lower back, oddly enough. I need to keep up my core work, though--that should help my shoulder. The handling is twitchier with the shorter stem, but was much better on Saturday's long ride with two full water bottles.

I'm still getting a touch of pain in my right knee, though this seems to sort itself out after a few miles. I'm still getting a hot spot on my left foot, so it's probably pedal-switching time (or will be), but it's not as bad as it was.

The one thing that has actually changed for the worse is the saddle. I can't tell if it's just a matter of adjusting to the new position, because every ride is a little different. The thinner-chamoised shorts are much better, but I'm getting pain and chafing in a pattern similar that from my old Selle Italia, minus the bulk of the back-of-the-leg chafing. This does not bode well...
