Continental Conti Valve Extender (Pack of 2)

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.

work great!

Good

They work well!!

The best extenders. None others worth buying.

Works great with my carbon wheelset. Especially a good decision if you have a set of tubulars that dont have exchangeable stems.

I installed these because I have 88mm deep carbon fiber wheels. There is absolutely no air leak, just make sure you use teflon sealer tape. I have used 60mm length version with 80mm valve inner tube but I could use the size smaller I guess (40mm) , but it is ok.

Works as advertised

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.

Easy to install but thats where the good part ends. The valve reciever end is thick and threaded and makes it difficult to clamp on many pumps. Gets clogged up easily with anti-puncture fluid, which makes changing tubes difficult because you cant deflate them all the way.
