Stan's Tubeless Exo-Core Valve

The Stan’s Tubeless Exo-Core Valve is a next-generation tubeless valve system designed to solve one of the biggest issues in tubeless setups—restricted airflow and clogged valve cores. Built from years of tubeless development, it delivers significantly improved air and sealant flow while remaining easy to service and maintain.

The standout feature of the Exo-Core design is its internal airflow system, which removes the traditional narrow valve core restriction. This allows for much higher air volume when inflating tires, making it easier to seat tubeless beads and add sealant without removing the valve. It also greatly reduces clogging from dried sealant, improving long-term reliability.

Another key feature is the modular, serviceable construction. The valve can be easily disassembled for cleaning or maintenance, helping extend its lifespan and keep performance consistent over time. The included TAP (Twist And Pull) cap is designed to stay secure while still being easy to remove, and often doubles as a valve core tool for added convenience.

The Exo-Core valve is also optimized for compatibility with modern tubeless setups, including rims with inserts, where traditional valves can struggle with airflow.

Key Features / Technical Details

• High-flow internal design for maximum airflow and faster tire seating
• Anti-clog construction allows sealant to pass freely without blocking the valve
• Makes it easier to inject sealant without removing the valve core
• Fully serviceable design for easy cleaning and long-term use
• TAP (Twist And Pull) cap for secure, tool-free access
