Challenge SuperLite Corsa Latex Road Inner TubeLatex inner tubes: Used in all high end tubular thanks to their low rolling resistance. Thinner and more flexible than butyl tubes.The use in open tubulars increases comfort and lowers rolling resistance. Latex is also more resistant to punctures. On the other hand it is a porous material therefore it requires daily inflation. Saving more than three watts per wheel over a butyl inner tube, this road bike tube gives you lighter and softer performance.Puncture protection is also greatly improved as latex extends and expands 7 to 8 times its original size, whereas butyl only about 1.5x meaning that latex is much, much more flexible and not immediately prone to punctures. Unlike the stiffer butyl, latex will first expand and wrap itself all around a protruding object and often isn't successful puncturing through even after working itself all the way in the tyre.The best performance and comfort combination is the latex inner tube with a handmade clincher, although the latex tube can also improve the ride of any other type of clincher.Replacing the standard butyl inner tubes (even superlight ones) with the Challenge seamless latex inner tube is by far the most affordable way of improving the performance and overall feel of your bike.Features: Use: Handmade Clincher Tyres Valve: Presta Removable Core Valve length: 48mm Size: 700 Tyre Width: 19mm-28mm Weight: 60gBuy Challenge Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
