Continental Conti Valve Extender (Pack of 2)

Dont buy the plastic extenders. These extenders will last.

Great !!!

Doesn’t leak and easy to install.

As long as you remember that these work only on tubes with removable cores, these are great. Try them out at home before you ride. Simply remove the valve core, screw these in, and put the valve core in the extender. Voila! They are well made and come with the mini, plastic valve core wrench. If you find a good deal on tubes with short stems with removable cores, these might come in handy, or if you have deep aero wheels that require an extension, these can help. Better to buy the right length stem to begin with.

They work well!!

Received defective product

Spendy, and I wish they came in black, but crucially, these worked, whereas the cheaper no-name brand did not.

I was looking for an extender for my presta tubes. This was not it.

If you have aero wheels you need these. Thread-in extenders are way better than the silly straw style extenders without the valve. But you need tubes with removable valve cores - Most Continental tubes work, and Q Tubes are cheap and just about all I have ever seen have removable cores.

Go big go latex! Use these get less flats and go low pressure
