A good fit for cyclists wanting a lightweight, frame-mounted lock for short-term parking, rural overnight stops or a car rack that already has its own lock.
The K-Traz C6 is a key-operated coiled cable lock designed for convenient, everyday bike security. Its flexible twisted steel wire is wrapped in a tough vinyl cover, helping protect the cable while being kinder to your frame than exposed metal. At 410 g, it is easy to carry for café stops, short errands and rides where you want a little extra peace of mind.
The included mounting clip attaches quickly to a compatible frame tube up to 30 mm in diameter, keeping the lock organised while you ride. The coiled design is compact to store, while still giving you useful flexibility when securing your bike to a suitable fixed point.
This is a basic-security lock for very low-risk areas, rather than a choice for prolonged parking in busy, high-theft locations. The Z Safe DS springless mechanism is designed to help prevent the bolt from blocking, making locking and unlocking smoother. For the best result, keep the mechanism clean and cared for, as moisture, dust and cold can affect operation.
