The chain is manufactured from special hardened 8 mm steel, providing excellent resistance to common mechanical attacks (cutting, sawing, levering). The links are heat-treated to maximise durability and longevity.
The mechanical combination lock offers 240 possible combinations, allowing simple and secure keyless operation. The mechanism is designed for frequent urban use and resists common tampering.
The chain is covered with a recycled PET sleeve, which protects the paintwork and bike components from scratches and wear. This material also provides a clean, responsible finish.
Specifically designed for the city bike, this chain lock combines robustness and practicality: it is suitable for securing frame and wheel to a fixed point in urban environments, daily. Its format allows easy storage on a rack or in a bag.
Finished in grey (GRAU) for a discreet, modern look, the lock features neat, durable finishes. Metal components and the textile sleeve are assembled for a resistant and attractive result.
