Review on Continental Cross 700X32 47C Bicycle Bundle by Robert Rick

What I like about it is that it has a washer that you can use to secure the valve stem to the rim. What I definitely don't like is the valve tip unscrewing. If you're traveling and have an apartment and use a CO2 cartridge for refilling, there's a good chance that the part of the valve that screws on will get stuck (freeze) and then the tip of the valve will come loose when you fill the CO2 -Unscrew the mechanism and all the air will escape. And of course you used up the entire CO2 cartridge. This has happened to me several times. This is not good. That's why I would avoid them.
