Remember how the valve stem on my rear tire snapped off in my hand and I needed to make a quick repair before my ride with Roger? Well, I used my last spare inner tube to get me on my way. This meant that I had no spare tube when I left for a quick pedal this morning.
Never ride without a spare tube.
To do so is an affront to karma and the Cycling Gods, who will smite you for your hubris. My punishment was administered five miles from home in the form of a moderately sized rock which I did not see while zipping along at 25 mph. Fortunately for me, my sainted wife was available to pick me up.
Now if you’ll excuse me, I’m off to the bike shop to buy some inner tubes.
