DT Swiss Tubeless Valve

The narrow base design is specifically engineered to fit rims with unique or tighter profiles where a standard, wider valve base might not seat flush. It ensures an airtight seal on rims that require a more precise fit to prevent air leaks.

While it is designed for tubeless-ready systems, the 'narrow base' specification means it is best suited for rims specifically designed to accommodate that shape. Always check your rim manufacturer's recommendations to ensure the base profile matches your rim's valve hole shape.

Yes, removing the core allows you to inject sealant directly into the tire through the valve stem using a syringe or injector tool. This is much cleaner and faster than unseating a portion of the tire bead to pour sealant in.

These valves are constructed from brass. Brass is chosen for its durability and resistance to corrosion, which is important given the constant exposure to tire sealants and environmental elements.

The 53mm length is a standard medium-depth size that works well with most alloy and shallow-to-mid-depth carbon rims. If you have very deep-section aero wheels, you may need a longer valve or a valve extender.
