EVO Presta Tube

This tube is designed specifically for 29-inch wheels with tire widths between 1.75 and 2.125 inches. If your tire width falls outside this range, you should look for a tube sized appropriately for your specific tire to avoid pinch flats or improper seating.

The removable core allows you to easily inject tire sealant directly into the tube for added puncture protection. It also makes it simple to install valve extenders if you are using deep-section rims.

A 48mm valve is standard for most mountain bike rims. However, if you have high-profile or deep-section rims, you may need a longer valve stem or a valve extender to ensure your pump head can attach securely.

The 0.9mm wall thickness is a sweet spot for trail riding, offering enough durability to resist common punctures while keeping the overall weight manageable at approximately 249 grams.

The threaded stem provides a secure grip for your pump head, which helps prevent the valve from slipping or leaking air while you are inflating the tire. It also helps keep the valve stem stable when passing through the rim hole.
