Trelock RS 560 NAZ Protect-O-Connect Frame Lock

The RS 560 frame lock was developed for demanding cyclists who refuse to compromise on technology and security. At its heart is a robust 8.5 mm hardened steel shackle, now available in a square version to significantly increase resistance to bolt cutters and saw attacks. In the event of tampering attempts, a special rotating mechanism ensures that the shackle locks itself inside the lock housing – a detail that makes all the difference when it matters. The housing has also been designed for maximum stability: instead of riveted components, a fully welded steel shell is used, which completely eliminates lateral attack points. The RS 560 is also fully compatible with the TRELOCK insert chain system. This allows the bike to be additionally secured to fixed objects with a single hand movement. The design is complemented by a newly developed high-security cylinder. Its asymmetrical milling, protected recesses, and improved coding technology make unauthorized attempts to open it virtually impossible.
