Had fresh tracks down edworthy park road this morning. I'm down to about 10 psi on my 700x30's, seems to be working I haven't fallen....yet. It definetly was the worst this morning, I was cyclocrossing over the snowbanks and the roads are just chop suey (we don't plow side roads here). Of course it doesn't help that after three days of snow build up, I have no breaking power. The bike sure looks neat though.
