Lock extension for frame locks

Decent frame locks are very difficult to break and therefore offer good theft protection; unless the thief can take their time, relaxed with a coffee in their workshop. For that you don't give the bike thieves a chance, it is always advisable to lock-on your bike (e.g. to a column, a grille, etc.).
You can simply plug the ZR310 into a compatible frame lock (e.g. the Trelock RS453), and thanks to a range of almost 2m you can connect any bike almost anywhere.

In use, the ZR310 is first wrapped around the target, e.g. a street lamp, the plug is pulled through the cable loop, and the plug is inserted into it Frame lock. Opening the frame lock with the normal key also ejects the additional cable.

For which bikes is this lock suitable?

The ZR310 is a reliable additional security device for all bikes, the only condition is the existance of a compatible Trelock or Abus frame lock.

Trelock - security thanks to German engineering

Trelock is a traditional German company that has been manufacturing reliable locks for decades. The continuity pays off in several ways: 1. the locks have continuously improved and today, thanks to "inner track milled" keys, they are de facto unbreakable without violence 2. ancient keys can still be reordered and 3. there is a German-speaking one in case of difficulties and competent help desk (which we have never had to use before).
