If you attempt to stuff this tube into a narrow 25c or 28c road racing tire, the excess rubber will bunch up, fold over itself inside the tire casing, and cause an immediate pinch flat or a blow-out when you pump it up.

If you are running deep carbon aero wheels (such as 45mm, 50mm, or 60mm rims), a 48mm valve stem will not protrude far enough through the rim hole for a pump head to clamp onto it. For deep carbon rims, you will either need a tube with a longer valve stem (60mm to 80mm) or you must install a threaded valve extender.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"11,15\"\u003eAuthentic Local Stock – Skip Port Surcharges \u0026amp; Customs Hassles\u003c\/h3\u003e\n\u003cp data-path-to-node=\"11,16\"\u003eAvoid the extreme frustration of trying to buy small essential spares, inner tubes, and tires from international online storefronts, only to face weeks of shipping delays, exorbitant courier freight minimums, or unexpected port clearance hold-ups at the border.
