I still think it's a good idea to have 12-27 teeth

Rainy quick morning ride. This hill looks flattened from the iPhone camera and Pano, but it's the one I always ride down with a curiosity for velocity (read: try to set speed records on). Not today. It was slick. Not zambonied ice slick, but slippery nonetheless. Modest speed of only 36. This is also the hill I broke my wheel on in the Spring. Stupid NJ potholes.
