Zipp Valve Extension 98mm for 1080 Wheels with Threaded Presta Valves - Black

A black 98mm Zipp valve extension for 1080 wheels, for use with threaded Presta valves. SRAM classes the 98mm as a fixed valve core extender, a type Zipp says works with most tubes and tubular tyres, whether their valve cores are integrated or removable. It threads onto the valve over a wrap of PTFE tape and tightens with a 3mm hex key until it stops; use fresh tape each time it comes off.
