If you're running deep carbon wheels, this is the only way to go. My 80mm(?) Inner tubes presta valve barely sticks out of the wheel. The Topeak is not only a perfect adapter, but after inflation, you can finger twist the tip and close the presta valve! And the Topeak also stays screwed in. Very quiet, seals when inflating, black in color blends in, highly recommended!

This valve extender is cool because you don't have to take out your existing core. Its very easy to use. Just wish I could have gotten a shorter one.

Used other extenders that didn’t hold air. These worked great and little to no air leaks from them.

Perfect for those with deep rims. I will keep mine in my ride wallet in case I need an extra tube with a short stem. Very nice seal. Easy to use.
