Challenge Corsa Latex Tube 700x28/35mm 47mm valve
Challenge sources high-grade natural Latex to produce the only seamless Latex inner tube on the market. Due to the lack of seams, these tubes have no bumps or added weight that commonly cause a tire to feel out of round. This also improves the overall strength of the tubes as seams are commonly the weak point on an inner tube.
Latex inner tubes are also very elastic, allowing them to initially wrap around a foreign object, rather than immediately puncturing.
Warning: because of its elasticity, installation of a Latex tube requires the skills of
an experienced hand. Latex tubes can be more prone to pinch flats if not installed properly.
