Schwalbe Tube

This tube is designed for 16-inch wheels with a width range of 1.1 to 1.4 inches. As long as your tire size falls within that range and your rim requires a Presta valve, it will be a compatible fit.

A Presta valve is thinner and has a small nut at the top that you unscrew to inflate, while a Schrader valve is wider and looks like a standard car tire valve. Check your current tube or the hole in your wheel rim; if the hole is narrow, you likely need this Presta version.

No, it is not recommended. Using a tube outside of its specified size range can lead to uneven stretching, thinning of the rubber, and a significantly higher risk of punctures or failure.

The SV4 designation refers to the tube's size and valve type, not the tire brand. You can use this tube with any brand of tire, provided the tire size and valve requirements match your wheel setup.

Presta valves are generally preferred for smaller rims, like those on folding bikes, because the narrower valve hole helps maintain the structural integrity of the rim. They are also easier to pump up with high-pressure floor pumps.
