Zipp Alu Knurled Valve Extender 91 mm

Zipp Alu Knurled Valve Extender 91 mm – Precision and function in one

When you ride high-profile rims, a reliable valve extender is a must. The Zipp Alu Knurled Valve Extender 91mm is designed to provide easy access to the valve, even on the deepest rims – without compromising on tightness, grip or aerodynamics. With Zipp, you get a lightweight, robust and well-thought-out solution that works – every time.

Designed for modern racing bikes

This valve extender has been specifically developed for use on racing bikes with deep rims, where the original valve is often not long enough. With a length of 91 mm, it fits perfectly on high-profile rims and ensures that you can inflate your tires effortlessly - both with a CO2 cartridge and a regular pump. An ideal solution for both training and competition.

Aluminum with knurled grip – more control with gloves

The knurled surface gives you optimal grip, even with wet fingers or gloves on. It makes it easy to screw the valve extender on and off, without the need for tools. At the same time, it is CNC-milled from lightweight aluminum, ensuring low weight and high precision - exactly what you expect from Zipp.

Airtight and vibration-proof solution

Zipp's valve extender features a precision thread and internal O-ring that ensures a tight seal between the valve and the extender. This means you avoid air loss – even at high pressures – and avoid annoying rattling or loose parts while riding. A reliable part that you can install and forget about.
