I've only ridden it twice. I went out on a short test ride last Friday but I only had time to ride on a flat rail-trail that was nearby, which was not a good test since I was going from a triple to a compact double. So the bike shop manager let me come back the next day for a longer ride that included hills. After about 25 miles and two hills for which I usually need the granny gear, I was sold (actually I was sold after about 5 miles, but I kept riding just to make sure

). The WSD geometry really is a better fit for me and the lowest gear on the new bike is pretty much the same as what I had on the old one, which is sufficient. And the roads were noticeably smoother with the carbon frame.
I got used to the SRAM shifters pretty quickly. I might even like them better than the Shimano brifters.
