not suitable for all wheels

On my bike, the part is really great. No frills, simple Bedinung, relatively simple installation (all as easy as on the video, it is then not). When wheel my wife it was complicated. The high wide handlebars combined with the shock absorbers and the hydraulic brake (soooo there) are here summarizes an insurmountable obstacle. Because if the prescribed distance for the radio signal is exceeded nothing works. I had at the end of the transmitter extremely high up on the fork mount (there where it is then wide). The mounting rubber must of course be extremely stretched at this point and then held exactly 2 days ago. Since the transmitter is with the rubber in the corner, and as long as my wife does not bother me that stuff remains lie. Why so clever designers for mounting on the handlebar with an option Schnellbinder offer (see video) but for the transmitter on the fork is not, an eternal mystery will probably remain.
