Basically makes sense that the handles are fixed to the outer end by the inner cone. A I think good and clean solution. Presupposes that the handlebar has round hollow ends. In an e-bike to my wife this is unfortunately not the case. Therefore, I send back the handle and buy her from the same manufacturer handles with croissants, so that even at the end äußernen mitt terminal is fixed.
Nevertheless, a full five points, because the product makes a really good impression.
