Continental Conti Valve Extender (Pack of 2)

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.

Fit good

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

Good quality no leakage

Exactly what youd expect. They install easily, and with a couple wraps of Teflon tape they lose no more than 20 psi/week with some Michelin tires inflated to 85 psi.

These work fine. No complaints. Far cheaper than what I could find locally.

Work but they leak like crazy.

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!). :-)

Dont buy the plastic extenders. These extenders will last.

I’m not sure what the issue is but these cause the valve to jam. I’m not sure if it’s by design but it’s problematic. This makes it difficult to let air out.
