Valve Core Tool

A valve core is a small, removable part inside your tire valve that controls the air flow in and out of the tire. It’s crucial for maintaining proper tire pressure, which affects your bike's performance and safety. Regularly checking and replacing the valve core can help prevent air leaks and ensure your tires are always properly inflated.

If you have deep-section rims or find it difficult to access the valve core for inflating or deflating your tires, a valve extension can be very helpful. It makes reaching the valve core easier, allowing you to maintain your tire pressure without hassle. If you struggle with tight spaces, consider adding a valve extension to your toolkit.

To replace a valve core, you typically need a valve core tool, which is specifically designed for this task. Additionally, a 5mm wrench may be required to secure any valve extensions in place. Having the right tools ensures that you can perform maintenance efficiently and without damaging your bike’s components.

Yes, you can remove the valve core yourself! Simply use a valve core tool to unscrew the core from the valve stem. This is often necessary for tasks like fixing a flat tire or adding sealant to tubeless tires. Just make sure to have a replacement core handy in case the old one is damaged.
