Continental Conti Valve Extender (Pack of 2)

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!). :-)

Seems like there good just didnt work for me. The threads didnt match

They work

Originally, I just tried screwing one of these puppies over the presta valve of a tire on an aero wheel, but that didnt work well at all. Prepared to award this seemingly miserable product a single star and a nasty review, I happened to glance at the DIRECTIONS, and realized the valve was to be disassembled BEFORE attaching the extender, and that the black plastic piece in the packaging was a wrench intended to accomplish this very purpose, and not, as I initially perceived, a roach clip misplaced by a Continental or Amazon employee. This is a great product that works wonderfully, even if the wrench looks like a piece of drug paraphernalia.

Best in the business if you need them. Most companies sell tubes with extenders already embedded to tube. These extenders are nice and secure, no leaks and last longer than the topeaks.

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

It looks good, but it doesnt fit any tire.

Go big go latex! Use these get less flats and go low pressure

Didnt screw flush down on latex tube, but seals just fine. Tool included is nice.

work great!
