Trelock RS 561 NAZ Protect-O-Connect Frame Lock/ZR 355 Plug-In Chain/Saddlebag Set - 100 cm

The RS 561 frame lock was developed for demanding cyclists who refuse to compromise on technology and security. If you want to park your bike or electric bike for a longer period of time, the RS 561 can be extended with the ZR 355 insert chain (included in the set). At its heart is a robust 8.5 mm hardened steel shackle, now in a square version to significantly increase resistance to bolt cutters and saw attacks. In the event of tampering attempts, a special turning 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 consistently designed for maximum stability: instead of riveted components, a fully welded steel shell is used, which completely eliminates lateral points of attack. The RS 561 is also fully compatible with Trelock's plug-in chain system. This makes it possible to secure the bike 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. The practical saddle bag is perfect for transporting locks or other accessories. For example, Trelock additional chains for frame locks can be easily transported with the bag. The surface material is weatherproof and the maximum load capacity is 2 kilograms.
