Trelock RS 561 Frame Lock 72mm Key Detachable - Black

The TRELOCK RS 561 ring lock sets a new benchmark in security and design, crafted for performance-focused cyclists who demand reliability and precision. Featuring a robust square 8.5 mm steel shackle, this lock offers enhanced resistance to bolt cutters and saws, while a smart locking mechanism activates through twisting in case of tampering — effectively deterring forced entry. The newly developed high-security cylinder is engineered for maximum protection against picking and drilling, with asymmetric key milling, intelligent cutouts, and a larger turning angle for smooth, accurate locking. Designed with user comfort in mind, the RS 561 includes a side-mounted locking button for intuitive operation, even with gloves, and a vertical key position for ergonomic handling. Integrated shock absorbers ensure quiet rides, while the compact, aerodynamic shape fits seamlessly on various bike frames. Unlike traditional riveted constructions, its fully welded steel housing minimizes attack points, making prying or pulling virtually impossible. Additionally, the built-in plug-in system allows riders to quickly secure their bike to fixed objects with a single motion, offering both flexibility and enhanced protection.
