Another thing I noticed is that very small adjustments in bike fit can make big differences. At first I had paid a lot of attention to articles I'd read about how to fit the bike. And that was a good starting point. But I've since found I'm more comfortable if I ignore some of the "rules." The seat post that came with my bike was not adjustable (could move the seat minimally forward or backward, but could not change the angle), but my husband bought me a Bontrager carbon fully-adjustable post a couple of weeks ago--just out of the blue, what a guy. I've been playing around with that a little. Perhaps I just haven't found the perfect angle yet to be comfortable in the drops.

Thanks for the shorts advice, though. That seems obvious, but I hadn't paid much attention to that--which is why I like this forum. There must be another thread for that, eh?
