These original replacement valve extenders from ENVE are designed to fit their deep section carbon rims, placing the valve far enough outside of the rim cavity to allow convenient access for inflation. ENVE valve extenders are designed to be used with removable core valves, common on high quality tubes and most tubular tires.
The 39 mm valve extenders are designed to fit ENVE's 45 and 3.4 series rims, the 55 mm extenders are designed to fit 65 and 6.7 series rims, and the 95 mm extenders are designed to fit 8.9 series.
Shipping ENVE Internationally
We can no longer ship ENVE products outside of the United States. We apologize if this inconveniences you.
Valve extenders are ideally installed using a valve core tool, or (carefully) with needlenose pliers. The valve's core must first be removed and then fastened into the extender. The resulting assembly is then threaded back into the valve.
