The truth of the matter here is that there are some designs out there on the market that just aren’t made for all types of handlebars. From what we have learned, if you have handlebars that measure to be just over 1 inch thick, you aren’t going to have much of a problem getting these devices to fit the way that they should. Users that have handlebars that measure over 1 inch thick, on the other hand, often run into problems. If you fall in the category of over 1 inch thick, be sure that you really dig into the product details to ensure that it is going to be large enough to fit.
