Kryptonite Ring Lock Anti-Theft Device

The Kryptonite KR SBX frame lock, ART2 SSF certified, secures the bike directly at the rear wheel. Its locking ring prevents the bike from being moved by rolling or being lifted. It features a plug-in capability, allowing the addition of a chain or cable to secure it to a fixed point, thus limiting theft by lifting. Kryptonite and AXA plug-in accessories are compatible. The key-retaining version prevents the key from being removed when the lock is open; a version without key retention is also available.
