Description

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.

Do you think the 19x28 would be OK with a 30-32mm cross tire? I would rather not carry the extra bulk of the 29-38.

Hey Steve,
Technically speaking you can run these in that tire, but its not a good idea. The more the latex stretches to cover the volume of the tire the more likely it is to pop. Additionally latex tubes are porous and leak air continually. If you stretch them further with a wider tire that becomes more of a problem.
I hope this is helpful. If you'd like to talk more about other options, please feel free to give us a call.

Super smooth ride

  • Familiarity: I've put it through the wringer

I switched from the Vittoria Latex tubes to these, much better. The Vittoria's are too thin, they are super light (about 50gm) vs these that are 70gm. I'll take the extra thick, but still pretty light ones - these :) I chalk them up pretty good with powder and install is easy. Yes, they loose about 30# of air overnight, but I always top off my air anyhow before every ride - just a few more pumps, and it's also good for your upper arm strength :) Make your bike ride just that much better - say 10% improvement on normal pavement. That's a pretty cheap upgrade. I do not notice any increase in punctures at all - am running Continental 4000S without any issues, other than being super awesome :)
