As soon as they're available I'll pick one up. If TomA is willing, I'll send it his way first for crr testing. There's a tacit claim of lower crr than butyl but somehow I doubt these will replace latex tubes. tl;dr: I'll probably put one of these in my race day flat kit for the sake of saving weight and space.
Sure, I'll test one...but, I've heard some of these claims before, like the Panaracer R'Air (which was only slightly
faster than a butyl tube)...so, "the proof of the pudding is in the tasting" :-)
But, depending on how they measured it, if it's 2X as "elastic" (and the important figure here is known as "resilience %") as butyl, then it's effect on Crr should be closer to latex (but not quite the same) than to butyl...we'll just have to see :-)
If it is even "on par" with good butyl, that's worth knowing for a variety of reasons. Including, yes, smaller flat kits.
The point is, ladies and gentleman, that speed, for lack of a better word, is good. Speed is right, Speed works. Speed clarifies, cuts through, and captures the essence of the evolutionary spirit.
