I am still relatively new to road cycling, but after all this "flip the stem" talk, I decided I would give it a try and see how it felt. As you can see from the thread title, it was sheer agony. I took a good half-hour ride in all, with a few hours of adjusting, and that was enough for me. My wrists and neck just weren't having it. (Bike was a Trek 1200, for what it's worth)

I figure this thread can join the countless others waging war over UP vs DOWN. Figured I'd throw in my two cents.
