For my taste, the collar is likely to attach to the handlebars have a slightly larger diameter. On a standard MTB handlebars to fit, but it is very tight and can no longer be completely pull the plug together. There remains a gap between bell and cymbal. Bombenfest it is, however, and that's important to me.
The bell has a really bright, almost shrill sound. When I have tried them in the apartment several times, my wife has almost stoned me. :-)
She is truly bloodcurdling, shrill, loud.
But also brings me to the "problem" of this bell. I've tested "in the wild", the "living object", ie pedestrians. Unfortunately, she is outdoors, mener Meiung after, not so good to hear, because it rings too bright. This is not necessarily perceived the same by people who walk in front of a. At least not if you already ringing off several meters Enfernung. If you are in the immediate vicinity of the pedestrian, this will hear a already.
Mir is the sound too bright and I find that he is not so easily perceived as a typical ringtone. This has confirmed to me the practice.
However, since the product has no technical or mechanical weaknesses and a good Eindruch do, I give 3 out of 5 stars.
