If my bike is crappier and my lock looks sturdier than the one next to me, I figure I'm safe. I actually have a Specialized branded U-lock from the late 90's. I've always sort of wondered if it was vulnerable to the same attack as the Kryptonite (or if it was even a rebadged kryptonite), but so far I've been hesitant to replace it because a) I'm cheap, b) I don't have the nicest looking bike and I park next to others with cables, c) it's the perfect size/length for me. Oh, and did I mention that I'm cheap?
