Continental Conti Valve Extender (Pack of 2)

Theyre great. I put plumbers tape on them as extra precaution, but Im not sure its necessary. I use sealant in my tubes and therefore buy tubes with removable cores for my deep dish rims. Anyway, these work great!

Easy to use no problems

Work but they leak like crazy.

Doesn’t leak and easy to install.

If you need valve extenders, these are the ones to get. Note that they do require removing the valve core, so be sure that your tires/tubes are compatible.

With the attached tool, these extensions are a breeze to install

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

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

Does its job well. It fits perfectly and holds air.

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.
