Overview

What Makes the Doberman the Go-To Combo Cable Lock?

The OnGuard Doberman Combo Cable Lock delivers heavy-duty theft deterrence in a self-coiling, easy-to-carry format. The 12mm-diameter cable resists cutting attempts while the integrated 4-digit combination lock eliminates the need for keys entirely. At 6 feet of reach, it handles a wide range of locking scenarios whether you're looping through a wheel, frame, or rack.

The self-coiling design keeps the cable tidy and tangle-free on the bike or in a bag, so there's no fumbling at the trailhead or coffee stop. It's a solid secondary lock for pairing with a U-lock, or a standalone option for lower-risk environments and quick stops where convenience is the priority.

The Doberman uses a factory-set combination. For a user-resettable option, check out the OnGuard Terrier.
