Valve Extensions
New for spring 2003, ZIPP hex key style valve extensions allow easier installation on tires and tubes for use with ZIPP and other Deep and Mid-v style rims. The new style ZIPP extensions are recognizable from older models by black anodization, a laser etched ZIPP logo and a 3mm hex key fitting in the pump head end.

Okay, so they aren’t stylish, but they are an aero-wheel must have item. Will fit any presta valve stem. Two sizes, small for rims up to 40mm and large for rims up to 60mm.
