snowman--where did this happen if you don't mind me asking?
I don't ever lock my bike up for more than an hour or two at a time...tops. And usually in busy places. I would never lock my bike up outside of a 2 hour movie, for example, and when I take it to work I bring it inside.
I guess I have decided that if someone wants to (and has the tools) to steal my components, they can have them. The frame is the most important part of my bike. If I have to risk someone taking my alex/formula wheels, so be it.
