Seamless 'one-piece' latex inner tubes provide 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 your comfort, lowering your rolling resistance, and helping to prevent flats. The tube also includes a removable presta valve core making them compatible with both inline and external valve extenders. Features:
Seamless & smooth latex material, no bumps at the valve
Improves rolling resistance and comfort
Strong and extremely elastic, thus very reliable
Lighter than standard butyl tubes and some superlight butyl tubes
Has a two-piece removable valve core for valve extender use
