Product details

What sets the Diamond Standard apart from the competition is Kryptonite's proprietary diamond coating combined with a high quality, heat-treated steel shackle that is the ultimate deterrent against thieves using angle grinders. Battery powered angle grinders are fast becoming one of the biggest threats to the security of your home - the Diamond Standard has been designed to resist this. The Diamond Standard has been designed from the ground up to destroy grinding wheels and deter criminals using these tools. Kryptonite's legendary New York series U-locks are the first choice for urban cyclists, and the Diamond Standard is the pinnacle of the range. This lock has been tested in real world conditions to ensure your ride is protected.

With the Kryptonite, a cut with the Flex was not enough to open it - that's a good thing! The fixation on the frame holder is cleverly solved with a rotating collar, so the lock can be easily accommodated on the frame. Very solid overall.
