Continental Conti Valve Extender (Pack of 2)

will be using these with the XLC Thorn Resisstant tubes

work great!

First off I want to point out that these didnt work for me as I thought they would have. I was setting up 50mm carbon rims, tubeless, forgetting the fact that I need the stems to be fastened to the wheel. These are not threaded to receive a holding nut and can easily be pushed into the rim causing air leakage. However, as a product these are a much better option than using extenders that screw over the presta core, where it is hard to check pressure with a standard gauge and needing to stick a piece of wire or spoke down the shaft the release air. The presta core screws right in to the stem allowing to easily achieve the a fore mentioned tasks. Definitely use a little Teflon tape on the threads before screwing into valve stem.

I appreciated finding these for a good fair price. They do what they are supposed to do and they are much better than other options like the silca valve extenders which can get stuck inside the valve port of some wheels (like my flo 60 carbon wheels)

Works as advertised

Does work at all.

Well made and don’t leak, also light weight.

Work great to extend valves for Zipp 808.

Doesn’t leak and easy to install.

These are easy to put in and they look nice. Thank you.
