Your tubes just got lighter.

You may not consider the lowly inner tube when it comes time to lighten up your ride. Sure, it isn't the difference between a steel frame and a carbon frame, but if you're counting grams, a pair of Challenge S.C. Latex Tubes are one of the least expensive ways to improve your riding experience.

Challenge Latex Tubes have a couple advantages over their butyl cousins. Latex is far more elastic and puncture-resistant than butyl. Therefore latex tubes are able to be made thinner than butyl tubes. This means that they're lighter weight, are more flexible, and accordingly, have less rolling-resistance. And, just as importantly, the aforementioned equates to a significant dampening of road vibration. The slight disadvantage with latex tubes, however, is that they are porous and naturally lose air a little quicker than butyl tubes. It's not really a big deal, but something worth noting. Because of this, we generally use our latex tubes on our race-day wheels and run butyl tubes for training.

The Challenge S.C. Latex Tube are available in the sizes 700c x 19-28mm and 700c x 29-38mm. Each tube has a 47.5mm-long valve.
