Die Schläuche sind unerwartet empfindlich gegen Überdehnung. In betroffenen Bereichen wird das Material porös, der Schlauch ist dauerhaft nicht reparierbar kaputt.Zur Überdehnung kann es schon dadurch kommen, dass sich der Schlauch geradezu klebend gegen den Mantel drückt, und sich von da aus in Richtung Felgenbett dehnt. So etwas in der Art ist mir zweimal passiert. Es scheint auch so, dass das unvermeidliche Zerren auf dem Antriebsrad hinten den Effekt verstärkt.Selbstverständlich war der Schlauch für Mantel und Felge groß genug gewählt.

They are reenforced around the stem. Installed easily, just put enough air in them to make them round with my own breath. Iver time, they do seem to loose air faster than a regular tube.

They have been taking a beating on winter gravel rides in temps between -5C and +5C. About 1000km in so far and no issues.They are installed in 43mm tires.

Order arrived in the time that was estimated, so no disappointment. Ideally it would have been quicker, but hey.Product as described. I bought the 700 X 38 size. Actual weight per tube was 40g, much less than my butyl tubes that were 160g. That's about the same weight savings as switching to entry level carbon rims but at a fraction of the price.These were my first TPU tubes. Installing easy easy, though they are so thin you have to check they don't get trapped and you end up with a pinch puncture. I freaked out inflating them, they make a lot of weird creaks and groans - even five minutes after. I'm assuming the tubes were some stretching and twisting into shape. I dropped the pressure to 20psi and rode around for a few minutes then reinflated. I fully expected them to be flat the next morning but had held full pressure. Just expect the weird sounds.Road feel is very different from butyl. Rolling resistance is noticeably lower, but the flip side is that even at the same pressure they feel a bit harsh. Proof was in the pudding, changing from butyl to TPU has taken three minutes off my regular 40 minute commute. Yes, latex may have slightly lower rolling resistance if you are prepared to pump them up all the time, and tubeless may be slightly lighter if you are happy with lower pressures. But TPU seems to be the sweet spot for me.Maybe you get better performance from a branded tube, but at a price. I'm really happy with these after a few rides and will see how they go longer term. Very happy with the purchase overall.

TPU TUBEを細いタイプを複数回購入、今回は太いタイプを購入、現状満足、耐久性はこれから。吸収性の意味が分からず未記入。

Tube was carefully installed using recommended methods by experienced person. Pumped up to rated tire pressure and left for one week with no use of bike. Spontaneous 1/4" rip opened in tube apparently due to poor quality. No evidence of any damage caused by installation or any other factor. Am now trying Sunlite brand. The tube looks better quality but will have to wait a little while before reviewing the Sunlite. It was worthwhile to have "free returns" of the defective YunSCM tube. Look for that option when buying bicycle tubes as a lot of other people have also had poor quality defective tubes from many of the brands sold by Amazon.

First time I have changed a inner tube. I like this brand and it came with 3 prying tools to remove the tire and install the new inner tube. It took me 20 min and the new inner tube worked well. My son loves riding is bike again they season.
