I have ordered the oversize handcuffs because my adapter to small standard has clips ... adapter is 12 years old but still top ... but now have a new bike with thicker handlebar ... so that the oversize clamps for me are correct ... I thought ... Unfortunately, the ring too big ... which means that I have a special size from the handlebar ago ... has nothing to do with the article .. but also I have inprovisorisch well solved the problem .... the principle of klickfix I find always good ....
