Aka - Rich, caught this little gem on my bike last week.
Walked out to my bike at the end of the day and said, "How's that chain running?" I said,"Great, hasn't worn or stretched much at all, better than any chain I've ever had." Then he said, "What's that?", pointing at one of the links. Riveted end of the chain pin busted, with the pin slowly making its way out of the back-side of the link...that would've been great going 90 down the freeway.
When it comes to reading text messages on his phone, he's damn near blind, but catching a small serious detail on a motorcycle, he's on it like stink on shit.
