Continental Conti Valve Extender (Pack of 2)

Good quality no leakage

will be using these with the XLC Thorn Resisstant tubes

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.

Excellent quality. You have to unscrew the presta value off the tube then attach the valve extender. Just as easy to pump up the tires as it is with the regular presta valves. I accidentally ordered a size too big for the depth of my wheels but even so, the extenders still look great on the bike.

I expected them to fit a standard valve stem, but they are some strange small extenders. Length was fine, but I have standard valve stems. Not worth returning them.T

It looks good, but it doesnt fit any tire.

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

work well and much better than the external valve extenders, just remember to use some white teflon tape on the threads to seal everything up well

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!). :-)

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.
