This one avoids needing valve extenders.\n0.9mm thickness is a good balance of durability and weight.\nRemovable core makes it possible to add sealant if someone wants a “tube with sealant” setup.\nAlways check rim tape before installing — many flats blamed on tubes are actually rim tape failures.\n\u003c\/div\u003e","brand":"Travail","offers":[{"title":"Default Title","offer_id":53142330933562,"sku":"GG-TUBE-TERAVAIL-70020-28-80PV","price":13.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/5735\/8394\/files\/TU1208-01-2.jpg?v=1773241086","url":"https:\/\/gograva.com\/products\/teravail-700x20-28-inner-tube-80mm-presta","provider":"Grava Adventure Corporation","version":"1.0","type":"link"}
