I bought this for my castle again remanufactured cross bike and am very satisfied. The connection to the spread in the cities post is straight forward with no problems. The length of 75 cm is sufficient, a bit more but could not hurt. But the castle is beautiful kompackt and can be easily snapped into the provided bracket. A pity, however, that you can not grow to the frame, the bracket. It fits in with me to the saddle quick release screw, where the castle now back hanging over en Porter. If one has a full time porter, the lock does not fit into the holder.
All in all, a good lock. The combination can be adjusted easily and the number wheels seen from stable.
