What happens when you realize the valves are too short
on your deep section wheels?
Are you going to buy new set of tubes?
Or tires with longer valves?
In this video, I will install the Continental valve extension kit
step by step
on my Dura-Ace carbon wheels to extend the valves by 40mm
The valve extension kit comes with 2 40mm Presta valve extenders
The tool to remove and install valve cores and extenders
And I also include the teflon tape to seal the valve treads
Firstly, remove the valve core with the tool
Apply the teflon tape on the extender
Remember to apply it the right way
Wrap the tape in a clockwise direction, it should be the same direction you
screw in that valve extender
Put in the valve extender
Put back in the valve core in the extender
and finishing it up by pumping the tire to the recommended pressure
Now do the same thing again with the other wheel
