Continental Conti Valve Extender (Pack of 2)

Really complements my Enve Wheels, these look and work great.

During the final lap of the Cedar Hill Race Festival in Cedar Hill, TX, the valve extender on my rear wheel failed, causing me to lose control and crash out myself and one other rider. Luckily the other rider is ok but I wasnt so lucky and ended up with a sprained shoulder and possibly a torn ACL (hopefully just a sprain). I have a video of the crash and you can see the tire instantly lose air, causing me to lose control and I have a picture of the tubes stem with whats left of the valve extender still screwed into the stems threads.

Works as advertised

This is a terrific product. My wheels have deep rims, and the tube for my front wheel only comes with a 40mm valve stem, which makes it difficult to get a good seal with the pump. I bought the 20mm valve extender and installed it with no problem in about 10 minutes. As suggested in several Youtube videos, I used a little bit of Teflon plumbers tape on the threads to ensure a good seal. Now, the pump engages with no problem, and the valve does NOT leak at all. I should have done this a long time ago.

They leak. Oh my, now I have a problem. Used them with new Veloflex Roubaix. Sure, everything fit. I even used plumbers tape around the threads for a better seal. But they leak a lot of air. And this is a real pain in the butt because now my tubulars are held down with glue tape. Ill be out $50 if I need to entirely remove the extender and replace with a new one.

These are great. Easy to install, leak free.

Works very well for my FLO wheels. Great for Deep dish wheels. Durability so far works very flawlessly. Put close to 1000 miles on them with no air leak. I recommend using Teflon tape to make a greater seal where it screws on. Recommended

Best valve extenders Ive ever used. Takes a little more work to install because you have to remove the existing valve core and put it in the extender, but worth the effort. Other extenders that dont have the valve core in them crack at the threads after a short life.

Doesn’t leak and easy to install.

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.
