The weather site current conditions suckered me again. Said -25C when I left, but after getting to university it changed to -28C. I thought it felt colder than -25, when its this cold you can feel every degree. I wore my Lake winter cycling boots and added chemical toe warmers. Despite being designed for a reduced oxygen inside boot environment, they were stone cold by the time I got to school. My toes were very cold by the time I finished my ride.
Otherwise I was dressed well for the temperature and didn't sweat much. The snow on the roads was packed super hard and is great / fast to drive on. Ride home is supposed to be a much warmer -9C.
I bought my bike in to thaw Monday evening and gave it a good cleaning, a re-lube and some new front v-brake pads. Last night I put it back in the garage to cool down. This morning the front brakes were frozen again. I'll have to spray something down the brake cable tonight.
