Hardened Steel Hex Link Chain with Integrated Lock

Updated 2026-09-05

This chain lock features 10 mm hardened steel hex links that provide excellent resistance to cutting and sawing. The 3.5 ft length offers enough flexibility to secure the bicycle to a wide range of objects, including large poles or multiple bikes. The hex shape of the links is specifically designed to make it much harder for bolt cutters to get a grip.

The integrated lock head utilizes a double bolt mechanism that secures the chain firmly in place. This locking system is paired with a high-security cylinder core that is engineered to resist picking and drilling. A durable fabric sleeve covers the entire length of the chain, preventing the steel links from scratching the bicycle frame or other components during use.

Five laser-cut keys are included with the lock, providing the user with several spares for convenience. The integrated design means there is no separate padlock to manage, making the locking process faster and more streamlined. This heavy-duty chain is an ideal choice for cyclists who need a flexible yet highly secure option for protecting their property in public areas.
