Last night was the coldest ride in a long time.
The reasons are complicated, but for the moment I have the old style black brake blocks on my front brake and salmon Continental Kool Stops on my rear brake. On the ride home my face was frozen, the bottoms of my non-skid Dansko clogs were frozen, the black brake blocks felt like ice cubes scraping against my rim... but the Continental Kool Stops performed like it was an afternoon in June. It was incredible. I'm fully converted.
Speaking of conversions, I have a set of Kool Stops for the front brake, I was going to install them with my new front wheel. More on that soon!
