Eleven Air chamber 700 x 23/32C in 40mm presta valve box

The inner tube is the real anima of the tire, which must work in synergy with the tire to absorb shocks and better deal with any type of deformation of the asphalt. The vast collection of Eleven inner tubes uses a special butyl compound that stands out for its maximum elasticity, consistency and the best performance in absorbing irregularities in the ground. Thanks to the reduction in specific weight, the Eleven compound is able to guarantee lower rolling resistance than other chambers available on the market, thus providing the best compromise between price and high product quality.
