Continental Conti Valve Extender (Pack of 2)

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

Good

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

I was looking for an extender for my presta tubes. This was not it.

Just what I wanted. Needed 48mm removable valve core tubes to clear my 88mm Carbon wheelset. Done forget to use Teflon tape for added piece of mind.

I expected them to fit a standard valve stem, but they are some strange small extenders. Length was fine, but I have standard valve stems. Not worth returning them.T

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.

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

This is a terrific product. My wheels have deep rims, and the tube for my front wheel only comes with a 40mm valve stem, which makes it difficult to get a good seal with the pump. I bought the 20mm valve extender and installed it with no problem in about 10 minutes. As suggested in several Youtube videos, I used a little bit of Teflon plumbers tape on the threads to ensure a good seal. Now, the pump engages with no problem, and the valve does NOT leak at all. I should have done this a long time ago.

Exactly what youd expect. They install easily, and with a couple wraps of Teflon tape they lose no more than 20 psi/week with some Michelin tires inflated to 85 psi.
