Autofocus Doesn't Work at 15 Below!

This morning was my coldest ride ever. I carried a temperature datalogger with me, and it recorded a temperature of -14.8 degrees F (-26 degrees C) near the mid-way point of my commute. Traveling at a sluggish 10 miles per hour created a wind chill factor of -35 degrees F (-37 degrees C). I was as prepared as I could be for those conditions, and I arrived at work warm... but exhausted. A co-worker took this picture of me with my cell phone camera that I carried in my backpack, but the cold seemed to kill the autofocus! What I wanted to show was that NO skin was exposed - because it would have meant frostbite within minutes. I wore a full face mask with ski googles, with an insulated bike helmet on top. I wore a windproof jacket and pants over 3 layers of fleece/polypro on my body. I wore "Thinsulate" ski gloves on my hands, and Sorel boots with two pairs of heavy socks on my feet.

What I learned is that I can dress up for the extreme low temps... but I wasn't prepared for the impact on the performance of my bike. It seemed like the grease in the axles and my 8-speed internal hub turned to mollases and it made it significantly harder to pedal. On flat, straight sections where I would ordinarily be easily cruising in the 8th gear, I was instead alternating between the 5th and 6th gear. To add even more difficulty, my nice warm Sorel boots are HEAVY. Lifting them up with each pedal stroke seemed to get more and more difficult through the ride.

The only real concern I had during my ride was when my goggles started to fog up with about 2 miles to go. It happened quickly. For the first 3-4 miles of my ride, the goggles performed perfectly. Then, the fog started creeping in - from the top down. By the end of the ride, I could only see clearly through the bottom edge of the lens. At these temps, taking the goggles off really wasn't an option, so I had to continue on - even with limited visibility. I'm going to see if applying an anti-fog treatment makes a difference on the ride home.

Anyway, it was an interesting challenge - but I won't be sad if I don't have to ride in temps this cold again this winter!

Finally.
I finally accumulated the parts I needed to put together my perfect Vermont winter commuter bike. I picked up the two crucial pieces from the Denver craigslist. It seems that there is a lot of honesty in the biking world, and I was able to get exactly what the sellers promised. I ended up with a used Surly 1x1 frame (completely built up as a nice single-speed) and a used Shimano Nexus 8-speed hub, built into a 26-inch wheel. Combine this with the studded Nokians I already owned, and my new MiNewt Mini-USB headlight (and tail lights, of course)... and I now have a dependable, safe commuter bike that will take me through all but the worst of conditions. I've been riding it all this week and LOVE it. Bring on the snow and ice. I'm ready.
