Had I ausfühlich information in the reviews about the product. The majority has rated the Farradhalter as well, so I ordered it. After unpacking, I want to try it right and have him screwed to my Cullmann Flexx Freestyle "arm extension". After I applied a little force when the bolts that bike mount is immediately broken (see photo). Property me now an aluminum Farradhalterung bought that is keeping at least ..... Conclusion: scrap, do not buy!
