Zipp®’s custom-designed valve extensions feature a 3 mm hex broach in the barrel
to guarantee a perfect seal when tightened and a raised machined head with a slight
bevel to ease installation of the pump head. A ridged section keeps the pump head from slipping.
Note: Valve extensions require specific installation,
so we highly recommend that you watch the how-to installation video
on the Video FAQ section of Zipp.com
and that you pre-install extensions on your spare tires and tubes before your ride.
