OnGuard Rock Solid

OnGuard RockSolid – Grinder-Resistant Bike Lock

The OnGuard RockSolid sets a new benchmark in bike security. Built from an advanced mix of ultra-strong materials and a layered defence system, it’s designed specifically to stand up against the most common and destructive tool in a thief’s arsenal: the angle grinder.

Unlike standard locks, the RockSolid’s hardened, shrouded shackle has been engineered to resist cutting, grinding, and brute force attacks. Every component has been tested to the limit, giving you a lock that doesn’t just deter opportunists, but actively defies determined attacks.

Despite its strength, the RockSolid is surprisingly easy to use. Its ergonomic design makes it practical to carry and handle, and at this level of security, it’s the lightest lock of its kind.

With five keys included, compact dimensions, and best-in-class resistance, the OnGuard RockSolid gives you real peace of mind – so you can leave your bike knowing it’s protected by one of the toughest locks on the market.

Dimensions: 90 × 175 × 14 mm
Keys: 5 included
