Price is for PAIR of Valve Extender
This valve extender from Boyd Cycling is the perfect way to inflate your tires with deep rimmed carbon wheels. The valve extender has a 3mm allen key slot at the end so you can really tighten it onto the valve of your inner tube. This makes it easy to pump up the tires without having air leaking all over the place.
We recommend to leave the valve extender on and tight all the time. Leave the valve core on your inner tube open (the force of the air pressure pushing against it will ensure that you won't lose air out of your inner tube). This way when it's time to inflate your tires you just have to put the pump on the extender and pump away, never worrying about taking on of off the extender.
The valve extender is 48mm in length. If you are using the 85mm clinchers you will want a 60mm long inner tube so have enough of the valve extender sticking out to pump up the tires with no problem.

Valve extender works perfect when installed properly.
I ordered a set to use with Boyd's 60mm clincher wheelset. As an admitted nube to deep dish and valve extenders, I did not install properly the first time (and they did not come with guidance). After locating a great article on extenders, I reinstalled using a generous amount of plumbers tape on the valve stem and they work perfect.
I have hade no issues with air loss (felt odd having to leave the valve nut in full open before screwing on extender) and they mate well with both of my floor pumps with no head slippage.
From an aesthetic standpoint, they mate perfectly with Boyd's black carbon wheels.
