Bicycle clothing is made from Lycra or Spandex, which are at least 85% polyurethane. Latex is made from rubber. It can be molded using liquid latex, or sewn, glued, or ultrasonically welded using sheet Latex material. https://www.sciencedirect.com/topics/chemistry/polyurethane-fiber https://en.wikipedia.org/wiki/Latex_clothing Hmmm... interesting looking bicycle attire. Buna I think you mean Buna-N, nitrile rubber, acrylonitrile butadiene, or NBR. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 Jeff, the ELASTIC bands in most bicycle clothing are pure latex. I think that I even see occasional warnings about this since some people are allergic to it. |

Sure, but the latex elastic rubber bands are covered with cloth or Spandex (urethane) and do not touch the skin. If you really want all Latex bike shorts, you could make your own: "Latex Bike Short Tutorial" https://www.youtube.com/watch?v=aRlQyDnL3M8 http://www.mjtrends.com/articles.php I haven't seen anyone wearing a shiny rubber B&D costume while bicycle riding, but it is possible: "Rubber Cycle Shorts" https://www.invinciblerubber.com/rubber-cycle-shorts Yech, not good. The shoelaces might get tangles in the gears. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
