If many years of bike adventures has taught us anything, it's never to leave your bike lock at home. Leaving your bike unlocked when you pop in to a corner store for some quick hydration can leave you stranded in seconds when an opportunistic thief wanders by, so keep your steed secure with the Kryptonite KryptoFlex 1265 Key Cable Lock. Its small and compact design makes it easy to bring along on any ride, and at just over 2-feet in length it provides enough cable to securely lock your ride to a tree, sign, or bike rack while you run in for a drink. The cable is made from 12-millimeter braided steel to provide resistance to cuts, and its lock head rotates 360-degrees for easier handling when you're locking up and unlocking. The lock comes with two reversible keys, so you can always keep one stashed in a safe place, in case yours goes missing when you're out on an adventure. As with all bike locks, the KryptoFlex 1265 isn't 100% theft proof.
