Tresor combo black square chain lock

Updated 2026-09-05

The Tresor 1385 is a versatile combination chain lock featuring 7mm square links made of specially hardened steel. This design provides significant resistance to cutting tools while remaining flexible enough for easy handling. The 85cm length is ideal for securing a bicycle to a variety of fixed objects in public spaces.

This lock utilizes a four-digit combination system, eliminating the need for keys and the risk of losing them. The digits are molded into the dials, ensuring they remain legible even after years of heavy use. A durable fabric sleeve covers the entire chain to protect the bicycle's paintwork from scratches and impact damage.

Finished in a professional black, this chain lock is both functional and discreet. The square link geometry is a specific security feature that makes it much harder for bolt cutters to get a clean grip compared to round links. It is a reliable choice for cyclists looking for a keyless, medium-security option for daily use.
