Continental Conti Valve Extender (Pack of 2)

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.

Fit good

Great for continental tires

Look very nice and have nice sealer on the threads. Unfortunately the male part of the extender broke off inside of my tube, leaving me to call an UBER back to thr group ride start. Have had my other extenders for years with no problems, just wanted something new looking. Oh well.

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.

When using deep dish wheels this is just the ticket item you need. Word to the wise always purchase removable core inner tubes.

Easy to use no problems

These seem great in theory, but they only seem to be compatible with Continental valves where the valve itself screws out of the valve stem. Trying to mount these on a Vittoria tubular tire in a deep section carbon rim just depressed the valve and made me lose all the pressure, yet wouldnt even thread onto the valve.

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).

Best in the business if you need them. Most companies sell tubes with extenders already embedded to tube. These extenders are nice and secure, no leaks and last longer than the topeaks.
