Continental Conti Valve Extender (Pack of 2)

Wish they made longer ones! But was able to screw two of these together and attached to my tubular. I have zipp 1080s and by using two of these extenders together I can air up and know my tire pressure too. These allow for you to screw in the valve to the extender unlike many of the simple straw extenders!

With the attached tool, these extensions are a breeze to install

Work great to extend valves for Zipp 808.

Very good and light. I remove a start because I find annoying that they force us to buy 2 when many people have a disc in the back and 808 in the front e.g.

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.

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.

They work

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).

Great !!!

Just make sure you buy plumbers tape (about $2 for a roll). Dont trust the rubber washers to hold air in over the long-run -- plumbers table should, though. Although, this isnt specific to the Conti valve extenders -- all valve extenders of this type are like that. ALWAYS BUY PLUMBERS TAPE!
