I'll have to find a lighter lock then. What I have is pretty heavy duty. But yea, I only need it to stop an opportunistic thief. Even my Kryptonite NYC Fuhgeddaboudit was broken. I had bike parking inside in my office, but they didn't want locks left on the rack so I'd leave the lock outside locked to a public rack. I did it for years. One day I ride up to get my my lock and it was gone. It just showed me how any lock can be broken. My guess is that someone decided to clean up all the dead locks because mine wasn't the only one on the block. Some of them looked like they hadn't been touched in years. Anyway, I bought a new somewhat lighter one since I had to carry it with me now, but it is still heavier than I want to carry 500 miles.
