Weather Out There

Today was another uneventful winter commute. Dry ground (save the open fire hydrant on Cambridge Street in Beacon Hill), high 30s, nothing special to report. I took the fixed gear today because the forecast was nice. The lack of fenders (see, they’re useful even in fair weather!) made me nervous for my clothing through the aforementioned water on the street.

Clothing: Heavy winter coat, wool gloves, waterproof shoes. No rain pants; messenger bag.

True to form, the fixed gear made me ride harder than usual (I love the way it pushes you up hills!) and the messenger bag constricted me a little. I managed to break a sweat.

I haven’t pumped my tires the entire month. This is a luxury you have in the winter: air escapes much more slowly when the temperature is below 50 degrees. (I’m sure it has something to do with the rubber becoming more porous, but that’s a tire engineer’s concern.) In the summer, if you aren’t pumping the tires once per week, then you feel as though you’re riding on a wet sock.

The reasons to stay on top of tire pressure are for performance (avoiding “wet sock” syndrome) and for “pinch flat” prevention. I also think that tires which are generally puncture resistant (from road debris) also perform better at higher pressure as they can scatter the debris as you ride instead of flopping down on its sharp edges.
