Latex Tube - 700 x 23-30mm, 47mm valve

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 core Presta valve making them compatible with both inline and external valve extenders.

• Handmade construction
• Has a two-piece removable valve core for valve extender use
• Improves rolling resistance and comfort
• Is lighter weight than standard butyl and some superlight butyl tubes
• Seamless & smooth latex material, no bumps at the valve
• Strong and extremely elastic, thus very reliable
