No matter what your reason is for riding a bike, protect it with the Kryptonite New-U Keeper STD with 4' Flex Cable to ensure your beloved steed never falls into the wrong hands. Built with a Hardened Performance Steel construction, the lock's double deadbolt resists twist-and-leverage attacks from hand tools, while the disc-style cylinder prevents unwanted picks and drills from breaking the internal locking mechanism. The included four-foot cable secures your front tire or other accessories to the frame when you park the bike in public. The lock's protective vinyl coating helps save your frame from scratches, and the included transportation bracket attaches to the frame so you can transport your lock with ease.
