Black integrated heavy duty chain lock

Updated 2026-09-05

This black integrated chain lock is designed for cyclists who need a lightweight yet secure option for quick stops. At 2.8 feet long, it is easy to carry while providing enough length to secure the frame to a standard bike rack. The integrated design means the lock head is permanently attached to the chain for ease of use.

The 7mm four-sided manganese steel links offer dependable resistance against hand tools and cutting attempts. The high-security disc-style cylinder is engineered to be pick and drill resistant, ensuring the locking mechanism remains secure. This combination of materials and design provides a solid level of protection for moderate-risk areas.

To prevent damage to the bicycle frame, the chain is wrapped in a weather-resistant nylon sleeve. The lock comes with two ergonomic keys that are easy to handle and turn. Its compact size allows it to be easily coiled and stored in a backpack or wrapped around the seat post during transit.
