The KryptoFlex 1218 Key Cable is a 12mm braided steel cable to be used in low-crime areas or as a secondary security measure. An advanced cylinder provides protection from picking and a sliding weather guard protects the cylinder from dirt, water and road grime. Everything stays in place while you ride thanks to the Transit Flex Frame Bracket, a tool-free, adjustable system that gives you plenty of mounting options.
Proper locking using a cable plus a U-Lock.
Place the U-Lock shackle around the pole, your bike frame and through your rear wheel. Loop a cable around your front wheel, bike frame, and onto your U-Lock shackle.
