OnGuard RockSolid U-lock

Defy thieves and angle grinders with the OnGuard RockSolid U-lock. This fortress of security features a massive 15mm hardened steel shackle with a patented coating, engineered to be virtually impervious to cutting. Its core strength comes from the X4P Quattro Bolt mechanism, which locks the shackle at four points to resist prying, jacking, and twisting. A bump-proof Z-Cylinder thwarts picking and drilling. While offering unbeatable security, its ergonomic design is the lightest in its class, and a double rubber coating protects your bike´s frame. Secure your ride with total confidence
