Silca built it around the weak spots of older TPU tubes, with a \u003cstrong\u003epatented valve attachment\u003c\/strong\u003e that mechanically joins the valve to the tube and a \u003cstrong\u003ewelded joint\u003c\/strong\u003e to stop seam failures. The \u003cstrong\u003ethreaded aluminum valve\u003c\/strong\u003e helps the tube resist heat from an electric pump, and a valve nut keeps it secure and rattle free. Folded, it measures 38 x 77 x 24mm and weighs 45g.\u003c\/p\u003e\u003cp\u003eSilca recommends this 50mm valve for rims under 40mm deep, and the version with a 70mm valve for rims 40 to 60mm deep. The valve core is removable, the tube works with rim and disc brakes, and each one 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 24 to 43mm 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":53763725787448,"sku":"AM-AC-065-ASY-0100","price":39.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0959\/8435\/3592\/files\/silca-ultimate-tpu-tube-hero.jpg?v=1794234087","url":"https:\/\/dialedcyclinglab.com\/products\/silca-ultimate-tpu-tube-700-x-24-43mm-50mm-presta-valve","provider":"Dialed Cycling Lab","version":"1.0","type":"link"}
