The 48mm stem clears a standard rim depth with room for a pump head, so the valve is easy to reach when you are fixing a flat at the side of the road. Teravail builds the \u003cstrong\u003eStandard Tube\u003c\/strong\u003e line with a 0.9mm wall, which gives you a tube that holds road pressure without adding much weight to the wheel.\u003c\/p\u003e\n\u003cp\u003eA \u003cstrong\u003eremovable Presta valve core\u003c\/strong\u003e means you can add sealant through the stem or replace a bent core instead of replacing the whole tube. It fits 650c tires from 20 to 28mm wide, so it covers narrow race tires and the 25 to 28mm widths most riders run now. 650c is the 571mm road size, not 650b, so check the sidewall before you buy. We keep this size on the shelf at the lab in both the 48mm and 60mm stem lengths because 650c tubes are hard to find on the day you need one. Choose this one for rims up to about 35mm deep and the \u003cstrong\u003e60mm version\u003c\/strong\u003e for deeper wheels.\u003c\/p\u003e","brand":"Teravail","offers":[{"title":"Default Title","offer_id":52956569731384,"sku":"210150TER","price":9.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0959\/8435\/3592\/files\/teravail-standard-tube-650-x-20-28mm-48mm-presta-valve.jpg?v=1789412129","url":"https:\/\/dialedcyclinglab.com\/products\/teravail-standard-tube-650-x-20-28mm-48mm-presta-valve","provider":"Dialed Cycling Lab","version":"1.0","type":"link"}
