Review on 🔧 Boost Tire Maintenance with Continental Conti Valve Extender: Pack of 2 by Keith Wolff

Don't waste money and fret using valve extenders that don't have the function of actually moving the valve. The ones that simply screw onto the end of your valve and rely on pressure to open the valve are a pain in the ass compared to these guys. Never had a glitch with this brand or its more sophisticated Zipp counterpart. Multiple bugs with other extensions closing the valve or not sealing the indentations etc. Get these and put your mind at rest. (You'll have to buy detachable valve core tubing, which costs a few bucks more. But you'll ride Zipps or some other expensive bike when you need it, so stop complaining about a few bucks for a decent tube!). :-)
