The new TRELOCK set combines the high‑security RS 561 AZ frame lock with a weather‑resistant saddle bag and the robust ZR 355 plug‑in chain to create a well‑engineered solution for cyclists.

The RS 561 AZ, with its 8.5 mm hardened steel shackle, fully welded housing and security level 15 rating, sets a clear benchmark for durability and everyday usability, particularly in urban environments and on e‑bikes.

The compact TRELOCK saddle bag, made from weatherproof material and measuring 200 × 90 × 90 mm with a maximum load capacity of 2 kg, offers an ideal way to carry accessories such as plug‑in chains safely and unobtrusively.

The ZR 355 plug‑in chain adds the crucial advantage of allowing the bike to be secured to fixed objects. Its 6 mm hardened steel links, protective textile sleeve and practical 100 cm length make it a powerful addition for demanding users who value maximum security combined with high flexibility.
