As always, thanks for the feedback. Checked LBS's in Naperville, IL area, no one carries Kryptonite. Performance has OnGuard. Told by one store that Kryptonite recalled, another said they were easy to pick, no longer carry. Kryptonite vs. OnGuard?? Also, is 4x9 the common size for backtire & frame to rack? I like the idea of Ulock connected to cable.
