Vittoria PV/Latex Road Tube

Como el pivote no tiene rosca se rompe la cámara al inflar, solo con poner la boquilla de la bomba de aire se rompe la cámara. Definitivamente no lo recomiendo. No solo me pasó una vez, me pasó doc veces con las dos cámaras que compré.

Yes, they'll lose air. I toured with these and found myself down 20 psi every morning of the tour. I'd pump them up to 100 psi and be down to 80 again by the next morning. With a good pump, this is not a big deal. Just plan on pumping them up every day that you ride. I don't ride often enough for that to be an ordeal, and even if I rode everyday, I'd just have my compressor ready to fill them.So why are they worth pumping up every day? They're light. I've read poly tubes are even lighter. I put them in a pair of GP5000 and they really roll. They're also reported to have low rolling resistance, maybe a couple watts lower than butyl. No flats after a couple hundred miles, even a few miles of gravel. If they keep going like this, I might stick with them over butyl -- and I just do recreational touring -- hey, why pump harder than you have to? It adds up over the long haul.Update: The front tube developed a leak at about 250 miles. There is a small crack about half a millimeter on the latex on the inner circumference of the tube. This would be against the Velox Fond de Jante rim tape, so not a puncture and not a pinch flat either. It would seem this latex is not that durable. I can patch it with another piece of latex and glue, but until I get around to it, I've put in a butyl tube -- all the LBS had in stock.

The picture shows a 29-in tube but the print shows 26-in tube. I thought it was ordering a 29 and received a 26 so I'm stuck with a useless tube. Have a nice day.

Até ao momento têm demonstrado ser de qualidade e estou a gostar bastante do comportamento da bike com estas câmaras. Apenas lamento que não tenham outras opções de comprimento de válvula (40, 60, 80 mm) para não ter de usar extensores de válvula.Boa relação qualidade/preço.Recomendo.

Just get a PU tube. They ballond
