Continental Conti Valve Extender (Pack of 2)

Once I understood how to use the included wrench to remove the valve core and screw into these extenders they worked like a charm. I have used two other brands and types and these by far work the best.

These work great and its nice they come in various sizes to get the perfect look as well as fit for the wheels. No excess air leaks, if it does leak, it is not noticeable, at least no more than brand new out of the box latex tubes. Product is quality and price was also fair.

Wish they made longer ones! But was able to screw two of these together and attached to my tubular. I have zipp 1080s and by using two of these extenders together I can air up and know my tire pressure too. These allow for you to screw in the valve to the extender unlike many of the simple straw extenders!

I finally figured out how to use these, sorry for my previous review, it was my fault for not asking.

Didnt screw flush down on latex tube, but seals just fine. Tool included is nice.

Worked well

Screws into Zipps tires easily and accepts the valve just as easy.

Doing what theyre made for, no issues would buy again. You need a removable presta valve to run these

Works as advertised

Using to adapt through some deep wheels. I put a bit of teflon tape on the original threads where the adapter connects, and on the adapter threads where the valve core connects. Has been holding air for months just the same as the original valve.
