The Anti-Theft-Device (long) from Ortlieb is a robust pair of steel cables with a sling. This allows you to easily and securely attach your Velobag to your bike using a separate lock (e.g. u-lock or padlocks). The perfect short version of theft protection is suitable for the Sport-Roller, Sport-Packer, Gravel-Pack, E-Mate, Vario and City-Biker bags.
