Well, that’s a type of flat I’ve never seen before
I was riding, for the seventh time, Kevin Brightbill’s Cuthbert Binns populaire, and when I was about 4 miles away from the end I rolled over a rough railroad crossing and instantly was slithering around on a completely flat tire.
When I pulled the tube and inflated it to look for the hole, I noticed a large quantity of air escaping from under a partially lifted patch. And when I peeled the patch off in preparation for replacing it, the tube fell apart.
I’m sure there are other bizarre bicycle component failures out there, but this one is a pretty good contender for the weirdest hardware failure ever.
