ABUS GRANIT XPlus 540

One of the cleverest D-lock designs ever. The state-of-the-art mechanism beat our lock picker. It outlasted our corrosion test. It stripped the standard saw blade, and took over 2 minutes of cutting with tungsten and 4 minutes with a power grinder.

Even after years on the street, GRANIT XPlus 540 is still the benchmark for shackle-style security. It’s a portable weight, too, but it’ll leave your wallet a lot lighter.

A high-quality lock. When it comes to high security, this is about as lightweight as it gets. A great deterrent if you’re locking up in a mid to high-crime area. We felt confident in urban environments. This lock lasts a long time.

A high-quality, very secure and well-made bicycle lock, which more than meets all of our requirements in the areas of practicality and security. It is very easy to transport but can reach its limits when the connection points are too wide.

This U-lock made a solid impression on us. Operation is simple and uncomplicated. The bracket loses a few points with us. You can only get the key out of it by unlocking it.

All the tools had a hard time with the GRANIT. Despite the massive impact of violence, it showed only minor damage and could still be used without any problems.

We just got this open, so it isn’t too hard to pick if you have the right tools, but I do think it’s certainly enough pick-resistance for securing a bike on the street.
