Continental Conti Valve Extender (Pack of 2)

The best extenders. None others worth buying.

I am sure you, like me, are thinking... do I really need this? I am also sure you, like me, learned that theres a specification on a tire tube that tells you the length of the presta stem. So I regret to inform you... yes its necessary if you, like me, bought tubes with too short of stems and realize it is not worth shipping the tubes back. Super easy to install. I had the Park Tool VC-1 tool but the included little wrench works fine. I used the included wrench to install the main cylinder. All hand tight and havent noticed any leakage. I am almost certain I can use them on the spare tube when the time comes (since I have 3 tubes but only two extenders).

Good quality no leakage

Works as advertised

Fit good

Easy to use no problems

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.

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

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.

will be using these with the XLC Thorn Resisstant tubes
