Unlike "over the top" style extenders, this Zipp Valve Extender Kit includes inline extensions that are installed between the existing valve stem and the Presta valve core, creating a more reliable seal. A rubber o-ring at the base of the extension prevents leaks. Available in variety of lengths to specifically compliment Zipp rims and many other manufacturers' designs. Includes 3 extensions and two 4mm/5mm valve wrenches per kit. Alloy construction.
Note: Inline valve extenders can only be used with Presta valves which feature a removable valve core.
Lengths / Zipp rim* compatibility:
27mm for 303 wheelsets.
41mm for 404 wheelsets.
65mm for 808 wheelsets.
91mm for 1080 wheelsets
*Sizing Note: These recommendations are based on a standard 32mm base valve. For shorter valves such as those found on the Zipp Tangente Tubular, it's best to order up one size.

Best deal out there
I shopped around and there are plenty of valve extender pairs for around $20 so adding a third and some wrenches for only a few dollars more was a no brainer. I installed two in a pair of Vittoria latex tubes and the third in a spare (Zipp's Tangente road tube). Installation was simple (I used Teflon tape) and it holds air equally as well or better (because the tape) than the normal latex tubes. Highly recommend if you're in the market for extenders, mostly because it comes with a third so you can have one installed on your spare already.
