Valves

When it comes to bike tyres, tubeless is the way to go for a smoother ride and improved puncture resistance, and to make the switch to tubeless, you'll need tubeless valves. These small but essential components are what allow air to enter and exit the tyre, while also keeping the seal tight to prevent leaks.

So how do tubeless bike tyres work? Unlike traditional tyres, tubeless tyres don't require an inner tube to hold the air pressure. Instead, the tyre itself creates an airtight seal against the rim of the wheel, forming a complete system. To achieve this, a tubeless setup requires a few additional components: tubeless-specific tyres that have a stronger bead to create a secure fit, sealant that is added inside the tyre to seal any punctures as they happen, and of course, tubeless valves to allow air to enter and exit the tyre.

When it comes to selecting tubeless valves, there are a few key factors to consider. The length of the valve stem should be long enough to protrude through the rim but not too long that it interferes with the wheel or tyre. This is particulalrly important on road bikes that use deep section wheels. Valve cores should be removable, which allows for easy access when adding or removing sealant, and the valve itself should be made from durable materials such as aluminum or brass to withstand the rigours of riding.

In summary, tubeless valves are a crucial component in the world of tubeless bike tyres. They allow air to enter and exit the tyre while also creating an airtight seal to prevent leaks. When selecting tubeless valves, consider factors such as stem length, removable cores, and durable materials to ensure a successful and safe tubeless setup.
