WTB TCS Tubeless Valves

Yes. The Max-Flow base is specifically designed to be compatible with tire inserts, ensuring that airflow isn't restricted when you're running a foam insert inside your tire.

No. The included valve cap features an integrated core remover, so you can easily unscrew the core to add sealant or troubleshoot without carrying extra tools.

These valves have a 44mm stem length. They are suitable for most standard mountain bike and gravel rims, but you should measure your rim depth to ensure the stem is long enough to protrude sufficiently for your pump head.

The valves feature an increased bore diameter, which allows for higher air volume and smoother airflow. This design helps prevent sealant from pooling and drying inside the valve stem, a common issue with narrower valves.

Not at all. The nut is ergonomically shaped and knurled, allowing you to get a secure, hand-tightened fit without needing tools that could potentially damage your rim.
