ABUS Pro Tectic 4960 Frame Lock

The case, the 8.5mm shackle, and supporting elements of the locking mechanism are all made of special temper hardened steel. The locking mechanism is in the lock body for an easy connection to the optional accessory chains and cables.
The 4960 can be mounted to the bike using either the cantilever brake mount option or the special "spannband LH" adapter for bikes without screw/bolt sockets.
