Challenge Latex Inner Tubes are the only seamless 'one-piece' latex inner tubes on the market providing a smooth, balanced ride with no pucker or bump like those found on other tubes. Latex tubes are lighter, thinner and more flexible than a butyl tube, increasing comfort, lowering rolling resistance, and helping prevent flats.
Please note the 48mm and 60mm aluminium valve stems are compatible with our Challenge Presta Valve Extenders which may be required for use with deep section rims.
