I rode a century with rhm earlier this year through the hills in NJ. At some point, the bike starts creaking with every stroke. I wonder what that is, but keep going.

The next day, I take the train back to NY city, and as I'm getting off the train, my wheel falls off the fork. It held in place by the front brake, so it didn't go too far. The quick release wasn't snugged down tight enough.
