Continental Conti Valve Extender (Pack of 2)

It looks good, but it doesnt fit any tire.

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

Screws into Zipps tires easily and accepts the valve just as easy.

Excellent quality and perfect for the job

will be using these with the XLC Thorn Resisstant tubes

Does the job and it does it well. Needed to extend my 51mm Vittoria latex inner tube to fit my Easton EC90 wheelset and this was the perfect choice. Easy to use and install.

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.

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.

Didnt screw flush down on latex tube, but seals just fine. Tool included is nice.

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.
