Challenge Latex Inner Tube
The unique Challenge seamless latex inner tube saves more than 3 watts per wheel over a butyl inner tube according to German, Finnish, Belgian, Dutch, UK and American testing.! The lighter, softer, more supple tube reduces rolling resistance and improves comfort, traction and cornering. 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!
