Review on Continental 700X20 25C Bicycle Inner Tubes by Jonathan Bennett

All three packages ordered opened, only one package did not leak immediately after installation. But the schrader rod is very weak and won't hold even after tightening the gland nut. Both of the other hoses immediately leaked out of the rubber where it connects to the stem. They had microcracks. If you don't have the money to burn cash and enjoy walking around the house staring at flat tires as you push your bike down the street, avoid this product like the plague.
