Just to say --
I posted this after I...noticed my rear getting a little sore from riding. I think there might even be a hemmeroid developing.
I usually place my hands on the more upright straight bar section, right around where they turn around.
So I tried drops, and it all seemed better. It is more awkward though, b/c you're leaning more forward, and I feel like I can't manuver as well as I can in a more upright position, but for some reason I seem to pedal harder when I'm in the drops, and my rear hurts much much much less. It's incredible how much less...
