OnGuard 8030 Doberman Combination Coil Cable Lock
Convenient Self-Coiling Security
The OnGuard Doberman Combo 6′ Coil Cable Lock (8030) delivers lightweight, convenient security for everyday cycling situations. Featuring a user-settable 4-digit combination lock permanently forged to a heavy-duty 185cm x 15mm self-coiling cable, this versatile lock combines ease of use with practical protection for medium to low-risk environments.
Heavy-Duty Cable Construction
At the core of the Doberman 8030 lies a robust 15mm diameter braided steel cable that extends to an impressive 185cm (6 feet) when fully stretched. This substantial length provides excellent flexibility when securing your bicycle to bike racks, lampposts, railings, or other fixed objects, whilst accommodating frames, wheels, and accessories in a single locking operation. The heavy-duty braided steel construction offers reliable cut resistance against opportunistic theft attempts.
Self-Coiling Convenience
The lock’s innovative self-coiling design automatically retracts the cable into compact coils when not in use, eliminating the frustration of managing loose cable whilst riding. An attached hook-and-loop velcro strap keeps the coils neat and contained during transport, preventing cable entanglement and ensuring the lock remains manageable when mounted to your frame. This thoughtful design makes the Doberman 8030 exceptionally practical for daily commuting and casual cycling.
Steel Ball Combination System
Security is managed through OnGuard’s advanced Steel Ball Click-Combo-Gear System, offering 10,000 possible 4-digit combinations that you can set yourself. This user-programmable combination eliminates the need to carry keys, making it ideal for cyclists who prefer keyless convenience or who regularly share bikes with family members. The robust steel ball mechanism provides reliable combination security whilst resisting common manipulation attempts.
Paint and Finish Protection
Every contact point on the Doberman 8030 is designed to protect your bicycle’s appearance. The entire cable features a thick vinyl coating that prevents scratches, scrapes, and paint damage to your frame, wheels, and components. The double rubber-coated lock head cover provides additional protection at the locking mechanism, ensuring that even the heaviest steel components won’t mar your bicycle’s finish during regular use.
Permanent Forging for Added Security
Unlike cheaper cable locks where the lock head can be separated from the cable, the Doberman 8030 features a permanently forged connection between the lock mechanism and cable ends. This eliminates a common vulnerability point found in lower-quality cable locks, ensuring that thieves cannot simply detach the lock head from the cable to defeat your security.
OnGuard Security Rating
The Doberman 8030 achieves an OnGuard security rating of 45 out of 100, positioning it as suitable protection for medium to low-risk situations. This makes it ideal for quick stops at shops, cafés, or well-monitored public spaces, or as a secondary lock to secure wheels and accessories when used alongside a primary high-security U-lock or chain lock for frame protection.
Mounting and Transport
The lock includes OnGuard’s All-Tube Twist Lock mounting bracket, which attaches securely to any tube diameter on your bicycle frame without requiring tools. Simply insert the lock’s integrated “T” fixture into the bracket and twist to secure. To release, push the orange lever and twist—carrying your lock has never been easier. The bracket keeps the coiled lock stable and accessible during rides, preventing rattling or movement.
