Challenge Latex 700x30-38C 48mm Presta Road Tube
🚚 Delivery Estimated between 09 December and 14 December.
Latex inner tubes are far more supple than normal butyl tubes. They adapt quickly to the tire changing shape while cornering and rolling. 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 Americal testing. Challenge produces 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 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.

I used these for my gravel bike that has Ralson 700*35C wired tires due to which the bike became heavy. At that time I could not buy light weight tires so I thought of using these latex tubes to lighten the wheels. It did the job perfectly. Mounting the tubes requires care and attention since you cannot use tire levers as the tubes are very fragile as compared to normal tubes. But once mounted properly, they reduce the weight of the entire bike, roll faster and are more puncture resistant though that may be due to the Ralson wired tires which are made of only of rubber without any nylon or silica. I will buy these latex tubes again for my gravel bike.
Completely satisfied with the purchase. Putting this review after 3 months of usage
