It aint that hard to figure out without directions. There's only four bolts, two nylok nuts and four plastic molded pieces. I don't know what kind of plastic this material is, but without too much effort I had no problem prying apart the handlebar clamp. But I can see where it might be too tough for some. Believe me, if this clamp got stressed to the point of snapping you would know about it. The handlebar bracket was a sloppy fit, but wrappng a few turns of black electricians tape around the circumferance of the handlebar between it and the clamp took up the slop. No slop after I tightened it. Solid as a rock. Now, my handlebars are only 22 mm diam. close to the brake cable mounts and then it flares up to 25mm in diam. towards the gooseneck. So now you know what to expect. I agree they should offer a larger diameter handlebar clamp and print a diameter spec to go along with it.
