In this XL version, the stem measures \u003cstrong\u003e60 mm\u003c\/strong\u003e and is intended for rims with depths between 30 and 50 mm. The coreless pass-through design delivers airflow up to \u003cstrong\u003e230% higher\u003c\/strong\u003e than a traditional Presta valve, while maintaining compatibility with Presta rim holes and pumps.\u003c\/p\u003e\n\u003ch3\u003ePass-through design and ball valve\u003c\/h3\u003e\n\u003cp\u003eThe heart of the system is a \u003cstrong\u003estainless steel ball valve\u003c\/strong\u003e with seals and O-rings, operated by an integrated external lever: it allows you to open and close airflow quickly and adjust pressure without removing any core, eliminating the issue of sealant-clogged cores. The Lite version head has an inner diameter of 3.3 mm and retains the Presta-style connection. The valve body screws onto the stem, so lengths are not directly comparable with those of traditional valves.\u003c\/p\u003e\n\u003ch3\u003eMaterials, compatibility and installation\u003c\/h3\u003e\n\u003cp\u003eThe body is CNC-machined from aerospace-grade \u003cstrong\u003e7075 aluminum\u003c\/strong\u003e with an anodized finish and is fully serviceable.
