The bar tape is Tresso Cloth tape available in many colors from Sheldon/Harris Cyclery. Then what you do after you put it on, is coat it with clear shellac with multiple coats. That gives it a sort of shiny gloss covering, depending on the number of coats, and prevents it from getting dirty from all the grease associated with bicycles. If you don't want the shiny look just put about 2 coats on. More if you want the gloss look. Be sure to get some ammonia to use in cleaning the brush off after each coat and finally rinse the brush with water, or you will have one stiff unusable brush when you go to put the next coat on. You can re-coat after about 1/2 hour, so you can see what you get fairly quickly. It is an old time French trick that I learned many years ago. All my bikes are done this way.
