The castle is very stable, easy to assemble and quick locking and unlocking. Super extent - a suitable cable we had the same system sold. Unfortunately, it took forever, until I found out how the cable is connected to the castle. Only a figure on the ABUS pages led me to it. Therefore, for all of us here an explanation:
On the lever with which to close the lock is a plastic cover that must away (usefully to the cable symbol). I could only get down the lid as I have deducted the Ganzel lever and have then pressed from below against the lid. When the lid is off, the cable is plugged in there and everything works great.
If that's clear there are at this castle nothing to complain about - in my view. Therefore, a star deduction for the bad description.
As a bike lock for quick locking and unlocking, I highly recommend it. With the additional option to it any where even attach particular with the appropriate cable / chain.
For safety reasons: When it receives the Abus Security Level 9. The highest level I have seen in Abus is 15 and have few and very expensive locks. So it's certainly on the value of the wheel, whether this is the right lock. We have rather cheaper wheels where the charm of this castle break is probably lower. However, a 2,000 bike I would not want to save it.
