With this -- I truly deserve a golden ticket into Club Tombay.

It's my second bone-headed mechanical move this week. As I mentioned in the "zip tie" thread, while installing a bike computer on another bike this week I accidentally zip-tied one of the spokes on my front wheel to the fork.

Not my week.
