Review on Continental Bicycle 700X20 25 Presta Bundle Sports & Fitness in Cycling by Dave White

I've been using Continental tubing for a long time and haven't had too many problems with it. Unfortunately, while quality control was a notable issue, in my last case it is a major issue. I bought a set of 5 80mm Presta valved 20-25c tubes and ran into a big problem. Of the 5, 2 had holes where the tubes were bent. That leaves me with only 1 replacement hose. I'm an advanced cyclist so with the number of miles I ride flat tires can be a daily occurrence. In general I have little to no complaints when the cameras are good outside of the box. In this case, however, I am disappointed and feel a little ripped off. I may have to look elsewhere for my whistles if the quality control is still that bad.
