These are soft leather with a self-adhesive double-stick tape on the back. They match our elkhide sewn-on handlebar covers and toe clip leathers. They protect your paint from chain slap and give your bike a finished look. In decades past, constructers actually brazed on fittings over which a leather strip was stretched. Our elkhide strips are the next best thing. Like all of our elkhide leather goods, they are cut by hand in the US.
