No matter if someone tries to break into the bike lock or the XPlus cylinder with conventional tools, or even special ones - they won't get very far. The built-in XPlus cylinder and the 8 millimetre specially hardened steel chain provide great theft protection. In order to protect the paintwork on the bike in the long run, the chain is covered with a textile sleeve. Even the keyhole has a cover to protect it from dirt and corrosion. Well secured, your bike can be parked with no worries.
