This style of lock is a popular alternative to the standard D lock thanks to the flexibility it offers when locking your bike; a handy feature when a uniform bike rack isn't available (think lamppost).

Unlike the other bike locks we have tested recently, this was the only one without an independent security rating, the K-Traz (inspired by San Francisco’s most rocky island prison) is, for what it’s worth, rated four out of five by Zéfal.
