LITELOK X1 is armoured with Barronium, a patent pending composite material that resists angle grinder attack by turning the grinder’s energy and force in on itself.

It offers at least 5 times more resistance than the best-selling, best-performing D-locks without adding any extra weight.

It is permanently fused to a hardened fine-grain high-tensile steel core which provides protection against all other commonly used tools such as bolt croppers, cable cutters, long bars, hammers and chisels.

It is the only full-sized armoured D-lock on the market and contains a host of clever design features that make it easy to use and carry so you can keep your bike secure against the most determined bike thieves.
