1. Place the valve core removal tool (included) on the valve’s core. Hold the bottom of the valve with one hand and turn the tool counter-clockwise with the other hand to remove the core (figs. 1–2)

2. Thread the extender into the valve. Use the included installation tool to tighten (figs. 3–4)

3. You can now reinstall the valve core into the end of the valve extender, again using the installation/removal tool (figs. 5–6)

4. Install the tube and tire as you would normally. You now have plenty of extension to use a standard Presta valve pump (fig. 7)
