These are the best latex tubes ever, period. Vittoria also makes very good ones, but these are seamless and generally lighter, and will give you even lower rolling resistance. Special care is advisable when fitting them because they are delicate. Using talc will help a lot in getting them properly positioned inside the tire and will prevent them from sticking to the tire or rim. Without talc, you can easily damage them unintentionally, and that is true. If you have multiple sets of wheels that you rotate but don't want all of them to be tubeless (due to the demanding maintenance of tubeless), Challenge tubes are the only choice for maintaining tubeless performance. Excellent product!
I don't recommend these tubes, Vittoria's are better. First, they are too short and therefore quite difficult to install first time. Secondly, after a few runs have removed - the entire inner side is covered with dotted bubbles, it seems that this is a technological seam during production. My rims don't have spoke holes (Bora) so it's not a wheel problem. Nothing like that happens with Vittoria, so I recommend them more - you can buy them right here. The only differences is the length of the valve & +/-10 grams. I personally don't feel the ease of rolling, it's just the fact that they saves 5 watts vs butyl. Of course you will need to blow every day, like as any latex tubes!
