Brass Removable Presta Tire Valve Core for Racing Bike

A Longly brass removable Presta tire valve core is a component used in Presta valves for racing bikes. Presta valves are commonly found on high-performance bicycles, including road racing bikes.

The valve core is the inner part of the Presta valve that allows air to be pumped into the tire or released from it. It consists of a small brass cylinder that houses a rubber sealing element.

Here are some key features and characteristics of a brass removable Presta tire valve core for racing bikes:

Material: The valve core is typically made of brass, which provides durability and resistance to corrosion.

Removable Design: The brass valve core can be unscrewed from the Presta valve stem using a valve core remover tool. This allows for easy replacement or maintenance of the core if needed.

Compatibility: The brass removable Presta valve core is designed specifically for use with Presta valves commonly found on racing bikes. It is important to ensure compatibility with the specific Presta valve used on your bike.

Rubber Sealing Element: The valve core contains a rubber sealing element that creates an airtight seal when the valve is closed. This ensures proper inflation and retention of air in the bike tire.

Precision Engineering: Racing bike valves, including the Presta valve core, are often designed with precision to minimize air loss and ensure efficient tire inflation. This is especially important for racing bikes, where tire pressure can have a significant impact on performance.

When replacing a brass removable Presta tire valve core, it is essential to use the correct size and ensure a proper fit. It is recommended to consult with a bike shop or a knowledgeable cycling professional if you are unsure about the specific valve core requirements for your racing bike.

Regular inspection and maintenance of the valve core and Presta valve are important to ensure optimal tire performance and safety during racing or high-performance cycling.

(Schrader valve):
commonly used on tires with lower tire pressure, such as mountain bike, folding bike, kids bike, etc. Schrader valve is mainly locked by internal pressure ，high pressure resistance, that is to say, air leakage is faster when the air pressure is not enough .It is very convenient to pump.

(Presta Valve):
Compared with the Schrader valve, the volume is more slenderer , It is often used in road bike，speed bike，racing bike and some mountain bikes.The advantage of the Presta valve is that it is more convenient to fine tune the air pressure, but it requires special air pumping equipment or through the tire valve adapter to use the commonly used air pumping device.
