Since the bicycle ages of old—adhesive-backed cotton tape. Use it on your hoola hoop, your kid's stroller, or like we and many other's do, on your bike. Makes a nice grippy area for the "aero" position on your dutch bike bars. Put it on your chainstay. Use as you will. Twine it and shellac it for near eternal preservation and utilizing one less piece of plastic.
If following conventional methods and wrapping your handlebar, one roll will do one side. You'll need two.
