Review by [email protected]Reviewed 12/29/20222 of 2 customers found this review helpful.Continental Valve ExtensionA Continental product that I found to be a little bit disappointing. Which is a first for me to say about Continental products. It works. But not as well as almost all other Continental products. My main issue is that one of the valves in the stem does not like to allow air past it while pumping up. The other one works fine, without any problems. Another issue is that one of them, even though there is a seal where it threads into the tubes valve stem, it leaks unless you use pipe threading tape. Once these issues are overcome though they hold air. So they can work well if they don't have the same issues as one of the 2 in the package of 2 that I bought. So you might want to consider purchasing 2 of the 2 packs just in case. But you might get lucky. Because it's very possible that the one that I got that was a problem could just be an aberration. I honestly don't know, because I only bought one of the 2 packs. It's probably worth trying, because I believe that Continental productas are typically high quality.

Review by AnonymousReviewed 12/27/2019by AnonymousPortland, OR1 of 1 customers found this review helpful.Excellent for deeper wheelsThese work great if your tube stem isn't long enough for deeper, aero wheels. Your tube needs a removable stem though.

Review by mbReviewed 2/27/2012by mbCompetitive RacerAustin, TX6 of 7 customers found this review helpful.This product represents an excellent value, you get 2 extenders and the tool for a very reasonable price.Unlike over the top extenders, the in line extenders enable you to accurately inflate your tires to the desired pressure. Additionally, if you ever need to use a foam sealant, the in line extender will yield better results. Make sure you tighten them properly to the tire stem using the provided tool and check for any leakage prior to mountinggluing your tubular tires.

Review by Vegas DaveReviewed 2/24/2012by Vegas DaveCycling EnthusiastLas Vegas, Nevada3 of 4 customers found this review helpful.Works great, easy to install and doesn't leak.I love these extenders. They are easy to install and they don't leak. I have used them over and over with different tires and I have even used tire sealent with them. You have to be careful putting them on that you don't turn too hard and ruin your tube or tire by twisting off the stem on the tube. Other than that they are great.

Review by chuck.grazianoReviewed 10/27/2011by chuck.grazianoCompetitive RacerNew Jersey9 of 10 customers found this review helpful.Great solution for aero wheels!These valve extenders are great quality and much more functional than the old style that fit over the top of the valve core. I love the way they work. My only issue is that I got the 30mm extenders, which are just slightly short for my Zipp 404 wheels.

Review by AnonymousReviewed 8/29/2013by AnonymousCycling EnthusiastNorthern Virginia1 of 1 customers found this review helpful.Superior product for tubulars or any valve with removable coreI bought these extensions to enable me to mount some older Vitoria tubulars on some aero rims. Since they work by removing the core from your existing valve, installing the extension, and then reinstalling the core into the extension, you could add sealant to the tires without removing them from the rims if you needed to. Also, they are beefy enough to hold up to pumping by hand.
