Hey Scrod,

Why would a bottom bracket unthread/come loose while riding?

My heart stopped a few weeks back when it happened on my leader, but luckily the threads on everything are okay. The drive side just seemed to have come unthreaded a little. I thought maybe I used too much grease, so I cleaned some off and it seems okay now.

Just want to satisfy my curiosity, I tried looking it up but no definitive answers.
