Thunder Works now offers three drink holders in black leather or tan leather (so I guess that makes six). We have a small one, a large one and now an adjustable one. It took me about 5 bad designs to get the adjustable one to work good. These will mount on any bar 3/4"-1.25" diameter. The mount is aluminum and is very secure and strong. Then a plastic bracket with 32 positions or angles attaches to that and holds the leather. We are using high quality cow hide. They are not cheap but they are very well made (in America).
