The ETRTO size from 25-622 to 35-622 is designed for tires with a 622 mm bead seat diameter and widths within the stated range. Its compact folded size makes it easy to carry as a spare during road rides.\u003c\/p\u003e\n\u003ch3\u003eSeven-layer TPU and replaceable core valve\u003c\/h3\u003e\n\u003cp\u003eThe micron-thin material is built in \u003cstrong\u003eseven sealed layers\u003c\/strong\u003e, a construction developed for air retention and durability. The TPU is uncolored to avoid surface imperfections caused by pigments. The valve base is slightly conical to improve seating against the rim; the internal threading allows the use of extensions or a replacement valve core.\u003c\/p\u003e\n\u003ch3\u003eInstallation precautions and brake compatibility\u003c\/h3\u003e\n\u003cp\u003eThis inner tube \u003cstrong\u003emust not be used with rim brakes\u003c\/strong\u003e: heat can cause a sudden loss of pressure. During installation, it must not be inflated beyond \u003cstrong\u003e0.3 bar\u003c\/strong\u003e to prevent excessive expansion before it is correctly contained inside the tire. A suitable rim tape and a valve hole with diameter corretto are required, avoiding pinching and twisting.\u003c\/p\u003e\n\u003ch3\u003eTechnical features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRange: Continental ContiTPU.\u003c\/li\u003e\n\u003cli\u003eMaterial: uncolored thermoplastic polyurethane.\u003c\/li\u003e\n\u003cli\u003eConstruction: seven sealed layers.\u003c\/li\u003e\n\u003cli\u003eCompatible sizes: ETRTO 25-622 to 35-622.\u003c\/li\u003e\n\u003cli\u003eValve base: slightly conical.\u003c\/li\u003e\n\u003cli\u003eValve: internal threading for extensions or replacement core.\u003c\/li\u003e\n\u003cli\u003eUsage limitation: not compatible with rim brakes.\u003c\/li\u003e\n\u003cli\u003eInflation during installation: maximum 0.3 bar before corretto containment in the tire.\u003c\/li\u003e\n\u003cli\u003eQuality control: performed on every inner tube after production.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003ch4\u003eCan it be used on a bike with rim brakes?\u003c\/h4\u003e\n\u003cp\u003eNo, Continental prohibits the use of ContiTPU inner tubes with rim brakes. Exposure to heat may cause a sudden loss of pressure.\u003c\/p\u003e\n\u003ch4\u003eHow much can the inner tube be inflated during installation?\u003c\/h4\u003e\n\u003cp\u003eDuring installation, do not exceed 0.3 bar before the inner tube is correctly contained inside the tire. This limit applies to the installation phase and does not indicate operating pressure.\u003c\/p\u003e\n\u003ch4\u003eCan it be reused after switching to a narrower tire?\u003c\/h4\u003e\n\u003cp\u003eNo, a TPU inner tube that has already been used must not be reinstalled in a smaller tire. In this case, Continental requires a new inner tube.\u003c\/p\u003e\n\u003ch4\u003eDoes the valve allow the use of an extension?\u003c\/h4\u003e\n\u003cp\u003eYes, the internal threading of the valve is designed for the use of extensions or for replacing the valve core.\u003c\/p\u003e","brand":"Continental","offers":[{"title":"700","offer_id":55148486623578,"sku":"0182731","price":23.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7139\/6534\/files\/64c7247e-1c2b-459d-9ae2-fb86992573f1.webp?v=1729178151","url":"https:\/\/www.all4cycling.com\/en\/products\/camera-daria-continental-tpu-road-valvola-presta-100-mm","provider":"All4cycling ","version":"1.0","type":"link"}
