I had a N-1 event today. Another Schwinn. Maybe I should’ve just gotten into Schwinn’s? No.

I should be happy. I’m not though. I liked doing the work on the Varsity and was proud that I made it rideable.

But as the buyer and I were chatting up the bike in the driveway. The rear inner tube went BANG!

I had aired it up in the cool garage earlier to 80-85 psi and stood the bike on its kickstand in the bright sun about 15 minutes before the buyers arrival. So I thought at first it was the heat from the sun over expanding the tire. After some reading on the physics of that it was highly unlikely the cause.

I’ve ridden the bike a couple of times on the tire/tubes. As recent as 2 days ago. They’re brand new Kenda tires and tubes. I used the rubber rim protector that came with the tire set. I didn’t see any burrs or other defects on the rim.

The buyer bought the bike anyway. Minus thirty bucks and I gave him a couple of spare tubes. Bad tire not holding the bead? Bad rim? Bad installation?

I felt terrible and hope I didn’t sell a problem.

I should be in a double celebratory mood. One less bike and 6 years sober today. Maybe I should go for a pedal on a bike I rehabbed.
