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.
