Monday morning, I loaded up my bike and noticed the rear tire was soft. I pumped up the tire and decided to work from home. There was my not-drive-to-work streak to maintain, after all.
Tuesday, the tire felt okay, I topped it off, and rode to work. A long ride during lunch and it was a little squishy on the way home, but I blamed the cold.
Wednesday morning, the tire was soft again. I drove to work and checked the tire in the evening. Still not entirely flat. Hmm…
My technique of fixing things is cleaning them until I discover something amiss. So I cleaned the inside and outside of the tire. I cleaned the rim, its braking surfaces, and even the cogs.1 Still nothing obviously wrong or pointy.
I pulled the rim strip to see if anything prickly was hiding beneath. And a spoke went feral. Somehow,2 a spoke head snapped off, allowing the nipple to poke the tube … maybe.
Regardless, the wheel needs fixed. Looks like my bike’s going to get some service.3
