Im all in on tpu and after 2 seasons on pirelli p-zero smartubes ended with a failure at the valve flange and unexplained leaks from rim side of the tube, and a few months on tubolito-S ended with a glass puncture and then tiny holes I was unable to patch on a new tubolito-S I have moved onto these. I was going to get the new Silca tpu tubes but after seeing these as the fastest tpu tubes on bicyclerollingresistance.com I went with these instead. Easy install. Feels smooth and fast. No problems yet. Valve resists connecting to my floor pump a little but not bad.

Wanted to pair up these tubes with the RS tires for summer riding KOM hunting. It tells you not to use with rim brakes, but one month in with some hard braking no issues. Wish there were more options for valve stem sizes as the 85 seems too long for my 50mm wheels. I usually use the pink tpu tubes sold on amazon for half the price and they have a 65mm valve option which is ideal, any savings in weight on the pirelli tubes is probably lost by extra valve length and not as aero.

Installed 2 and one was flat before the first use. Found a small hole so not much confidence especially at this price
