The Abus Steel-O-Flex Tresor 1360 effectively protects your bicycle against theft with its 4-digit code. The overlapping steel sleeves, 20 mm thick, encase the inner steel cable like a hard metal shell. Once you have selected your custom-configurable number code, you can secure your bicycle without a key using the Steel-O-Flex Tresor 1360. A special scanning protection hinders attempts to crack the code through manipulation. At the same time, you can set the correct combination in the dark using the embossed digits on the dial.
