The great advantage of the ABUS lock is the massive lock cylinder and the well-designed chain that seems assured of steel covers in addition. Very important: The soft textile jacket protects the frame of the bicycle, so that it does not scratch.
I looked at the bigger and heavier models of Abus. These were my all too unwieldy and heavy. The above model seems to be there a good compromise.
The lock can also be good to wrap around the frame of the wheel to transport, can be seen on a carrying bag that you often need the larger models, without.
CONCLUSION: Makes a very robust, has not yet been cracked so far, although the bike even outdoors at night.
