Review on 🚲 2-Pack Continental Presta Valve Tubes (42mm) by Vincent Pavelko

Great tubes. In my opinion if you have a problem with these tubes. This is a user error. Be sure to get some air in the pipe as you begin the installation process. Not much, just enough to fit in the tire. Little. Thus, the pipe does not interfere with the installation tools. Do not use a screwdriver. Use appropriate tools. If you are using tubes with a Presta valve, tighten the stem nut once you have installed the tube in the tire. This will prevent the tire from moving when mounted. Simply tighten with your finger. Don't put animals on it. Make sure you have the correct size pipe. If all this is done, the lamps will work properly and last a long time.
