Specialized 700 x 20-28c, 80mm Long Valve Innertube - Grey

Specialized Presta Tube 80mm valve 700 x 20/28 Lightweight, durable and affordable. The Specialized Presta Tube 80mm Valve 700 x 20/28 inner tube offers outstanding performance and reliability thanks to Specialized's 'mold cured' method of production. This production method allows Specialized to manufacture their tubes to a thickness of only 0.8mm... more, whereas most of the competition are 0.9mm thick, a thinner tube is a lighter tube. This reduction in thickness does not affect reliability, Specialized's curing process allows for a more even cure and reduction in granularity of the butyl rubber, ultimately leading to a stronger tube. A longer valve version of the Standard Road tubes designed to accommodate aero profile rims. Also available in 32mm, 48mm and 60mm length valves
