More importantly, Latex Rubber has significantly lower coefficient of damping which means that when latex rubber is stretched or flexed, it returns to shape faster and with less energy loss.\u003c\/p\u003e\n\n\u003cp\u003eWhat does this mean for an inner tube?  Latex inner tubes are generally 2-5 Watts (per tyre) more efficient at 30mph than tubes made of other materials. They are harder to pinch-flat and offer superior ride quality, especially when combined with supple, low rolling resistance tyres. This tube has been sized to fit tyres measuring 24-30mm, which will equate to 23-28mm tyres used on modern wider rims.  Valve stem length is 42mm and will work in all modern disc wheels.\u003c\/p\u003e\n\n\u003cp\u003eSpecifications:\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eOptimized for tires measuring: 24-30MM (Tyres marked 22-28mm when used on wide rims, or tires marked 24-30mm used on older narrow rims)\u003c\/li\u003e\n\t\u003cli\u003ePremium Latex\u003c\/li\u003e\n\t\u003cli\u003e42mm Aluminum alloy valve, 10 grams lighter than Brass alloy valves and works in all modern disc wheels\u003c\/li\u003e\n\t\u003cli\u003eRemovable Presta valve core\u003c\/li\u003e\n\t\u003cli\u003e78 grams\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Silca","offers":[{"title":"Default Title","offer_id":43853742178499,"sku":"SI005916","price":53.85,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/2609\/5299\/files\/SI005916.jpg?v=1722996299","url":"https:\/\/fb539f-da.myshopify.com\/products\/silca-latex-tube-700x24-30-valve-length-40mm","provider":"The Odd Spoke","version":"1.0","type":"link"}
