JoeBlow Mountain II Floor Pump

The TwinHead® design features two openings that accommodate multiple valve types: Presta, Schrader, and Dunlop. This versatility means you can use the same pump for different bikes, making it a convenient choice for cyclists who own various types of bicycles or ride with friends who may have different valve systems.

Presta valves are typically found on high-performance road bikes and are narrower with a screw-on cap. In contrast, Schrader valves are wider and resemble the valves found on car tires. If you're unsure, check the valve type on your bike's tires; if it has a small, slender valve, it's likely a Presta, while a wider, spring-loaded valve indicates a Schrader.

Yes! The TwinHead® design allows you to inflate bikes with Presta, Schrader, and Dunlop valves without needing multiple pumps. This feature makes it an excellent investment for cyclists who want a single, reliable pump for all their biking needs.

An analog gauge provides a clear visual representation of tire pressure with a dial and needle, allowing you to easily monitor inflation as you pump. The base-mounted design ensures that you can read the gauge comfortably while inflating your tires, helping you achieve the optimal pressure for a smooth ride.

If your pump has a TwinHead® design, you won't need an adapter. The TwinHead® can directly accommodate Presta valves, making it easy to inflate your tires without any additional equipment. Just switch to the appropriate opening, and you're ready to go!

Dunlop valves are commonly found on certain bicycles, especially in Europe. They are similar to Presta valves but have a different design. If you have a bike that uses a Dunlop valve, ensure your pump has the TwinHead® feature to inflate it easily.
