Truly universal and actually sufficient.

I bought my Abus 54 / 300HB (Granit X Plus) the holder. Actually I wanted halters the castle with the textile support and the stirrup clamp 27348, but this universal mount enough really. The two parts are combined in different ways (for use of the lock parallel or offset from the tube), the retaining screws securing both parts against each other - so beautiful Klickfix (with the other solution) and at first glance is the inserted into the holder lock ( As another reviewer remarked correctly) remain secure against an (obviously nonsensical) theft if I secure my bike on the fly in front of a small business with eye contact to the outside with wheel lock.
When mounting a bit of courage and experimentation is necessary until you have the right provided backing for the diameter of the selected brace on the bicycle. But then keeps's bombproof. Before good clean!
