Yes. Because these tubes feature a removable valve core, you can easily inject your preferred tire sealant to help prevent flats or seal small punctures.

Yes, these are designed specifically for clincher tires. They are built with a 622mm ISO diameter, which is the standard size for 700c road and gravel wheels.

The threaded valve stem allows you to use a rim nut to secure the valve in place against the rim. This prevents the valve from rattling or pushing back into the rim while you are attaching your pump head.

A 32mm valve is best suited for standard, shallow-profile rims. If you are riding deep-section aero wheels, you will likely need a longer valve or a valve extender to ensure your pump head can attach properly.

The 0.9mm wall thickness strikes a balance between durability and weight. It is robust enough to handle daily training and rougher road surfaces while remaining light enough to keep your rotating mass low for efficient acceleration.
