Silca says swapping butyl tubes for TPU can save 200g or more in your tires, and that TPU has all but matched the rolling resistance of latex tubes or a tubeless setup at a fraction of the weight of latex. A \u003cstrong\u003epatented valve attachment\u003c\/strong\u003e mechanically joins the valve to the tube, and a \u003cstrong\u003ewelded joint\u003c\/strong\u003e is there to stop the seam failures older TPU tubes were known for. Folded, it measures 58 x 77 x 26mm.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003ethreaded aluminum valve\u003c\/strong\u003e helps the tube resist heat from an electric pump, the core is removable, and a valve nut keeps it secure and rattle free. Silca recommends the 50mm valve for rims under 40mm deep. It works with rim and disc brakes, and each tube comes with a patch and an alcohol wipe for a quick repair. Silca says it fits in its \u003ca href=\"\/products\/silca-mattone-seat-pack-standard\"\u003eMattone seat pack\u003c\/a\u003e along with an Elettrico inflator, tire levers and a multitool. It is for riders on 700c or 29in tires from 44 to 64mm wide who want a smaller spare in the bag or a lighter tube in the tire.\u003c\/p\u003e","brand":"Silca","offers":[{"title":"Default Title","offer_id":53763725951288,"sku":"AM-AC-065-ASY-0300","price":39.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0959\/8435\/3592\/files\/silca-ultimate-tpu-tube-hero_dfd12e9d-e202-4444-8629-79fdcad7783f.jpg?v=1794234092","url":"https:\/\/dialedcyclinglab.com\/products\/silca-ultimate-tpu-tube-700-x-44-64mm-50mm-presta-valve","provider":"Dialed Cycling Lab","version":"1.0","type":"link"}
