The Essential Quick-Fix for Tubeless Maintenance

The Stan's NoTubes Replacement Valve Core is a small but critical component for any tubeless rider's toolkit. Over time, tire sealant can accumulate and harden inside a valve, restricting airflow and making it difficult to seat a bead or adjust pressure. Instead of replacing the entire valve stem, simply swapping in a fresh, clean core restores your system to factory performance in seconds.

Crafted from durable brass, these cores feature a standard Presta interface and a removable design that allows for direct sealant injection through the valve stem. Whether you are troubleshooting a slow leak or preparing for a big race, having a few spare cores on hand ensures you won't be sidelined by a stubborn, clogged valve.

Key Features:

• Removable Presta Core: Allows for easy maintenance and direct-to-tire sealant injection without breaking the bead of your tire.

• Universal Compatibility: Designed to fit all Stan's NoTubes tubeless valve stems and most other standard removable-core Presta valves.

• Durable Brass Construction: Built to withstand the corrosive environment of tire sealants and provide a reliable, airtight seal.

• Easy Installation: Can be quickly replaced using a standard valve core tool or a pair of needle-nose pliers.

• Optimized Airflow: Replaces fouled cores to ensure high-volume airflow, which is critical when attempting to seat tubeless tires with a floor pump.
