Kryptonite Serie 4 1055 Mini


The Kryptonite Evolution chain lock is probably the highest security chain lock from Kryptonite that can still be described as truly portable.

I’m reviewing the Kryptonite Evolution Series 4 1055 Mini here because it’s the shortest, which also makes it the most portable, and (for me at least), the most usable too.
