We guarantee that this product has been tested by the manufacturer. It is true that it is resistant, of proven quality and provides a significant period of optimum life, thanks to its perfect seal. I also appreciate his French Presta valve 36/40 mm that allows me quick and reliable inflation at 8 bar. As to even say he holds "months," I would not go that far, but certainly it lasts much longer than other brands I have been totally abandoned, that I agree to recognize it.
Besides, perfectly satisfied by the constant use of this tube, I intend to order from this site soon saw that my bike shop ceased operations starting to retire and leave me, now somewhat in the embarrassment for replenishment. Only comment I wish to make here, but that has no direct relationship to the quality, covers the delivery costs deemed excessively high, too expensive, if not more than the product itself or else to benefit to free you will need to order at least 25 to purchase ...
