The innovative flat-top plate design of the Evolution compact disc lock is short in height allowing the lock to attach to the rotors spider in more than one location requiring 2 cuts to be defeated. It has a 13mm Hardened Max-Performance steel shackle that resists bolt cutters and leverage attacks as well as a HARDENED DOUBLE DEADBOLT design giving additional protection against twist attacks. The Evolution compact disc lock also includes a handy bright orange REMINDER CABLE to prevent riding away while disc lock is engaged.
