Description
Lightweight, durable and affordable. The Specialized 40mm Presta Valve, 700x20/28, Road 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 competition is 0.9mm thick. This reduction in thickness lowers weight and rolling resitance but 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.
Equipped with a 40mm long valve and sized for 700c tyres with a width of between 20mm to 28mm, as well as traditional 27x1 1/4 tyres.
