The lock cylinder uses advanced Switzerland technology with an anti-drilling piece, only 0.3-0.6mm thickness and snaked shaped, which can effectively prevent technical stealing.

The lock body is made of hardened steel with heat treatment, it is strong and has high toughness, which prevents it from being thumped, sawed, sheared, and drilled.

The connecting plates are made of 5mm thickness hardened steel alloy, with only a 0.2mm gap. They are hard to be damaged and prevent several types of potential attacks. The unique design allows links to rotate smoothly around the axis, without jamming or squeaking.

Outside the link, a 3mm high-quality PA coating is used, which effectively prevents scratching your bike paint. It also protects the lock body from rust and corrosion.
