Trelock RS 561 AZ Protect-O-Connect Frame Lock

The Trelock RS 561 frame lock was developed for demanding cyclists who do not compromise on technology and security. At its heart is the robust 8.5 mm hardened steel shackle, which now features 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 side attack points. The RS 561 is also fully compatible with TRELOCK's plug-in 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.
