Panaracer Fietsbuis, Schrader-ventiel, veel verschillende maten, 35-48-60 mm ventielen, enkele of twee stuks

These tubes are decent enough and seems to last for a few months. I bought 4 of these and only one has gotten punctured by a piece of glass that went through the tire if installed correctly and maybe with a tire puncture liner these will last longer. The presta valve on these seems well built.

When it comes to bicycle inner tubes I don’t have any brand loyalty but do try to stay within known makes – Continental, Kenda, Schwalbe, etc. As far as overall quality and value are concerned, the Panaracer tube in this review is well within the same category as the aforementioned brands. Barring the inventible punctures, these tubes have lasted me for years and thousands of miles and only replace them if they get damaged beyond repair. This Panaracer is a replacement to the unrepairable Kenda tube on my gravel bike – (The offending thorn tore through the seam!)I see some folks complain about flats. For a good quality tube within its reasonable shelf life and hasn’t been exposed to harmful substance or UV, there are only a handful of reasons for flats – Punctures, Pinch-Flats or Sizing mismatch/Incorrect Pressure/User Error. Manufacturing defects can happen on any brand but are quite rare. Most flats I suffer are punctures from goat-head thorns and as far as I know, there are no inner tubes of any make and model including the so-called “self-sealing” Slimes are immune to goat-heads. Tires are thicker than inner tubes. If a goat-head or any sharp object can punch through a tire, it will most definitely punch through an inner tube. You may also hear some people complaining about weight. Unfortunately, these are the cyclists who weigh anything and everything with a postal scale and believes 200grams is unacceptably heavy on a bike because their average speed has slowed down by 0.002mph - I'm not one of those!Anyone looking for a replacement tube or a spare to take on a ride, this Panaracer is as good as any Continental, Kenda, Michelin, Schwalbe, Sunlite, Vittoria, Tubolito, Etc.

No hay mucho qué decir, son camaras igual que cualquier otra cámara y sirven para guardar aire, no tienen ninguna ciencia. No se les sale el aire, no tienen problemas en las válvulas ni se me han roto de las uniones. Definitivamente volvería a comprarlas pues no les he encontrado algún defecto

Nice tubes and well packaged. One thing - make sure you select the proper stem length, even if it is a "damaged box". I was happy to order a tube that cost a bit less because it had been returned (and the tube was in perfect condition) but it was not as clear to me ordering that way what the stem size was. Just make sure it says EXACTLY what you are looking for and you will have a great product.
