ChallengeLatex Road Tube(Return to Product Page)

Bought 2 of these, both failed in the same place where the valve connects to the tube within a month.

The latex tubes are very light and you can feel the advantage, however, the tubes lose air very quickly, I have to pump them up before every ride (daily).

Good so far, paired with 25mm Vittoria open Corsas Makes for a fast comfy ride.

Bought 2 that installed easily and rode great, but both developes small holes that were hard to find and patch.

I have these tubes paired with Challenge Grifo open tubulars and they are a great combo. I'm 195 lbs and run these at 30 PSI front and rear for cyclocross.

I can feel the difference in ride quality between these and butyl tubes. It takes some getting used to as more compliance can almost feel like your tire is going flat. But once you get used to running lower pressures and letting the tires do their job everything really hooks up.

Worth the money. Spend it and get some nice tubes. Your base miles will thank you.

I found this tube difficult to mount with the unused Strada Bianca. I think the Strada Bianca needs to stretched and formed a bit first with a butyl tube.

Solid, even manufacturing, removable valve cores - longevity, and 74gramseach - cheapest and best upgrade to any ride :)

After reading a few reviews, I was still very skeptical about these tubes. They cost 2-3 times more than regular tubes and some have said that they don't hold air that well. Here are my thoughts:

1. I liked the way they feel. Very supple, and they seemed to hug the contours of my wheel when installing them (better than butyl tubes do)
2. After pumping them up to 60 psi, I found that they lost 20 psi overnight. It's no big deal. I always pump my tires to my regular pressure, 100 psi, before every long ride
3. At the beginning of the ride, my wheels felt somewhat heavier than usual. It may just be something that I imagined
4. An hour into the ride, I felt like the wheels were at higher pressure. I know this happens, but I almost never notice it. But this time it did feel like I had a stiffer ride. I liked it!

I'm still not quite sure if these observations are more in my head than quantifiable differences. Mainly I wanted to rebuke the claim that these tubes are more prone to problems when installing them. There's also a feeling of quality in these tubes, from the packaging, talc, unusual color and clear cap.

Use these tubes mounted in Conti Supersonic tires (I know, not exactly a typically heavy duty training ride tiretube combo). Gawd! Do these roll! And keep on rolling!
