Review on VeloChampion Road Bike Inner Tubes 700X18/25C With Presta Valve by Danierl Temple

I think i am now my 8th one of these and I won't buy again. I thought the price was good and have bought a bunch but they give out and burst all the time with no puncture of the tire. Even on a street bike if you hit a section of rough road or a pothole expect a flat tire. They seem to burst and give out on the inside between the wheel and tube. I think 6 of the 8 I have used so far have burst with no sign of damage or puncturing of the tire itself. Most often they give out near the value on the inside. I ride on average about 100 miles per week, so flats occur regularly but I am fed up of the tubes bursting and won't buy any more of these.
