    Every gram counts.

    The Challenge S.C. Latex Tubes are significantly lighter than standard butyl tubes for the less rotational mass and lower rolling resistance when you're competing and racing against the clock. They're also more elastic and resistant to punctures than regular butyl tubes. However, because of their highly porous nature, they tend to lose air more quickly than their butyl counterparts, making them better suited for your race-day wheels.

    Be aware of poor tube construction/safey

    • Familiarity: I've used it several times

    used two challenge tubes with high hopes. visually Ok.installed without issues.pressured to 100 psi.both failed catastrophically with same failure mode within days of each other. pressure was released instantaneously after approx 50 miles of riding when the valve interface to tube body bond failed....very poor performance/bad manufacturing and safety concern for a costly tube.returned for exchange with another brand and hope they inform the manufacturer of the safety/manufacturer flaws.they should not market these with such high failure rates and defects

    gave us the same sinking feeling as the sudden splits failure in the michelin ultralight repeated failures we've seen

    Terrible Tube

    • Familiarity: I've used it once or twice and have initial impressions

    I agree 100% with Timothy S. Furthermore, I question the sizing. They are suppose to be 700, but seem more like 650s. It was a royal PITA trying to install one of these tubes. It then exploded at around 80 psi when trying to inflate it. I thought perhaps that if I stretched the second tube before installing I'd have better luck. Tried doing that, but the latex is so thin in spots that huge bulges would develop before the tube would stretch. Might see about returning the second tube, but seems like such a hassle for only $18. DO NOT BUY!!

    Worst latex tubes I've ever owned

    • Familiarity: I've used it several times

    I've been using latex tubes for a long time and have never had the issues I've had with these tubes. I thought I'd give them a try when I bought 2 sets of the Starada and Strada Bianca tires.

    These are the issues:
    1) when slightly inflated so as to rub a little Talc powered on them and install, all of them have at least one area with very thin latex. This area bulges like a balloon.
    2) When installed properly (talc powder, partially inflated when installed, twisting the tire when its seated on the rim) the tube will either explode at 60 lbs or inflate properly and explode on the road.

    I bought 8 of these in both the 30mm size and the 25mm size. Every single one exploded.

    Lastly, I'm running these with the Challenger Strada tires.

    I would not trust these tubes with my life. Most frustrating latex tubes I've ever owned.

    Tom would love these!

    • Familiarity: I've put it through the wringer

    Very light, no flats, actually hold pressure better than expected but pump them as a precaution before daily rides. In combination with 320 TPI tires rides lighter and better than tubulars. So far, so good.

    Holy Lightness!!!

    • Familiarity: I've used it several times

    Man these tubes are light!!! Love them, no problems with flats at all, just be careful when installing them, they can pinch easily. I chalk them up before install, and it goes in just fine!! Just wish they were a little cheaper ;)

    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 :)

    The pic appears to show a removable valve core, just want to confirm this before purchasing.

    Thanks.

    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.
