My wheel (250) was stolen outside the house, the ABUS Ivera was cut with a bolt cutter. So - it can be cracked or be cut. Too bad that I have already disposed of the castle, otherwise would have a picture taken and uploaded. The 2 star's that the panel does not scratch the wheel and that the castle - from cracking or cutting - made a very solid impression. So, if someone wants the wheel, then he will do this (or perhaps other) tank locks do not stop ....
