Deep section wheels need longer valve stems than what comes standard on most tubes, and valve extenders bridge that gap without requiring you to source specialty tubes for every rim depth in your collection. The Zipp Tangente Valve Extender threads onto existing Presta valves to add the reach needed for 60mm, 80mm, or deeper rim profiles. The design uses a brass construction that matches the threading pitch of standard Presta valve cores, creating an airtight seal without the leak points that plague cheaper aluminum alternatives.

The extender works by removing your tube's existing valve core, threading the extender onto the valve stem, then reinstalling the core into the extender's tip. This puts the sealing surface at the outer end where your pump head connects, rather than buried deep inside the rim where access becomes impossible if something loosens. The brass body adds minimal weight while providing the durability to survive repeated inflation cycles and the occasional overtightened pump chuck.

Installation requires a valve core removal tool, which Zipp includes with each extender. If you're running tubeless setups, the same extenders work with removable-core tubeless valves, giving you flexibility across wheel and tire configurations. The threaded connection means you can swap extenders between wheels as your rim depths change, rather than committing to specific tubes for specific wheelsets.... Read More
