Free Worldwide Shipping
GravCore™ strikes the perfect balance between strength and practicality. Built with 5.7 mm steel links, a durable black protective sleeve, and an upgraded lock core with anti-pick technology, this is the lock for riders who demand more than just basic security – without the bulk of a heavy-duty chain.
🔗 Reinforced 5.7 mm Steel Chain
Made from tough, high-grade steel links, GravCore™ offers a solid layer of defense against cutting tools. At 5.7 mm thickness, it’s the smart middle ground – stronger than lightweight options, but easier to carry than ultra-heavy locks.
🛡️ Durable Black Sleeve Protection
Wrapped in a sleek black fabric sleeve, the chain is protected from the elements and won’t scratch your frame. Subtle, stealthy, and made to last in urban environments.
📏 Available in 3 Lengths

⚙️ Smooth & Reliable Operation
Designed for everyday use, the lock opens and closes effortlessly while keeping your bike safe. Built to resist tampering, tension tools, and casual thieves.
