Specialized Standard Presta Valve Tube

Yes, this tube is specifically designed for 27.5-inch wheels. It is compatible with tire widths ranging from 1.75 to 2.4 inches.

No, this is a standard butyl rubber tube and does not come pre-filled with sealant. You can add your own sealant if you choose, but it is not required for the tube to function.

The molded construction ensures the butyl rubber has a uniform thickness throughout the entire tube. This eliminates weak spots caused by excess material or thin walls, leading to better reliability and a more consistent rolling feel.

A 40mm valve is a standard length suitable for most traditional mountain bike rims. However, if you have deep-section aerodynamic rims, you may need a longer valve stem or a valve extender.
