Continental Conti Valve Extender (Pack of 2)

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.

Works great for an 808 size wheel when combined with a 80mm valve stem with RVC. No problems. Thank you!

Best valve extenders Ive ever used. Takes a little more work to install because you have to remove the existing valve core and put it in the extender, but worth the effort. Other extenders that dont have the valve core in them crack at the threads after a short life.

Does work at all.

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!

Good quality no leakage

Works well, requires a removable valve core

I used these to help clear my 80mm carbon wheelset. Its worked excellent so far, and they held up through the ironman races I did. No air leaks.

use plumbers tape to get a good seal. otherwise works great. Put on 88 and 60 deep rims

Exactly what was needed for the deeper Zipp rims. Removable valve core tubes and these extenders make everything so much easier. I wish you could buy different lengths in a set, but this was a huge improvement. 48mm valves on the tubes and 60mm extensions fit the 808 rear wheel well but are long on the 404 front wheel.
