ABUS’ Pro Tectic Frame Lock is good for quick errands in safe neighborhoods. Its extra-wide opening2.48 inches wide and 4.25 inches highlocks your rear wheel, preventing your bike from rolling or being ridden, while accommodating a variety of tire/wheel sizes. The case, 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, providing an easy connection to the 4960 accessory chains and cables (each sold separately), and letting you lock your bike to a fixed object. The 4960 can be mounted to the bike using either the cantilever brake-mount option or the spannband LH adapter for bikes without screw/bolt sockets.
