Specialized Inner Tube 700c x 20-28 Presta Long Valve - Grey

Specialized Presta Valve Road Inner Tube 48mm 700x20/28 Lightweight, durable and affordable. Specialized Presta Inner Tubes offer 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, whereas most of the c... moreompetitors 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. Suits all tyres up to 28c width as well as traditional 27 x 1 1/4 tyres. Also available in 32mm, 60mm and 80mm length valves.
