Continental Conti Valve Extender (Pack of 2)

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.

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

Easy to use no problems

Dont waste your money and give yourself aggravation using any valve extenders that dnt have this feature of actually moving the valve. The ones that just screw on to the end of your valve and rely on pressure to open the valve are a royal pain in the butt compared to these guys. Never had a failure with this brand or its harder to fine equivalent from Zipp. Multiple failures with other extenders that close the valve or dont seal wells etc. Get these and give yourself some peace of mind. (Youll need to buy tubes with a removable valve core, which cost a couple bucks more...but youre riding Zipps or some other expensive wheel if you need these, so quit complaining about a couple bucks for a decent tube!). :-)

Works perfectly with my 88mm wheels. I have 88mm carbon wheels with 80mm tubes. Adding these extenders gave me plenty of room to inflate my tire without the stem extending out to much.

This was the perfect valve extender for my Boyd wheels that are 90mm. I was having a difficult time getting the correct air pressure in the tire with the extenders that came with them. I like how the continental extenders allow for the valve to be exposed so my bike pump stays connected when inflating the tire.

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.

This work great with deep dish carbon rims. The ridges on the tip also allow a good grip when your filling up with your presta valve pump. Make sure to put on pipe sealant teflon tape before screwing these on for a better seal. This is the 3rd set Ive bought. Also make sure to get the proper length so that you have room to place the pump on your valves stems. I tend to go with a little longer valve extender because I have a 60, an 88 and 100mm different deep rims.

I finally figured out how to use these, sorry for my previous review, it was my fault for not asking.

Does work at all.
