Cheap, generic inner tubes are often made by taking a flat strip of rubber, rolling it into a tube, and gluing the edges together, which creates a heavy, uneven seam. Under pressure, that seam becomes a rigid line that resists stretching, causing the rest of the tube to expand unevenly, which leaves thin spots vulnerable to flats. \u003cb data-path-to-node=\"11,11\" data-index-in-node=\"407\"\u003eContinental mold-vulcanizes every tube in a fully round, continuous cylindrical mold\u003c\/b\u003e, ensuring perfectly uniform wall thickness across the entire tube. This method provides superior structural elasticity, handles higher pressures easily, and rolls with less resistance.\u003c\/p\u003e\n\u003cp data-path-to-node=\"11,12\"\u003e\u003cb data-path-to-node=\"11,12\" data-index-in-node=\"0\"\u003eCan I use this specific Race 28 Wide tube if my tires are marked 700x35c or larger?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"11,13\"\u003eNo, this model is custom-mapped for a maximum expansion boundary of \u003cb data-path-to-node=\"11,13\" data-index-in-node=\"68\"\u003e700x32c\u003c\/b\u003e. While high-grade butyl rubber has excellent elasticity and can technically stretch to fill a larger space, forcing a 32c tube up to a 35c or 38c gravel casing will stretch the rubber walls far too thin. This drastically drops your protection against pinch flats, makes the tube highly vulnerable to small trail thorns, and can cause the base of the valve stem to rip away under high torque loads.
