Our standard butyl innertube features a 0.9mm wall thickness that strikes the perfect balance between weight and durability, providing excellent value-for-money. The S/V Schrader Valve (American Valve) with a 40mm valve length is perfect for trouble-free double wall rim compatibility, while the P/V Presta valve (French valve) with 48/60/80mm length options provides compatibility for a wide range of rim depths.
