Compatibility: Ensure that the valve cores you purchase are compatible with Presta valves. Check the diameter and threading to match your existing valve stems.
Quality: Look for valve cores made from high-quality zinc alloy materials to ensure durability and longevity.
Quantity: Determine the number of valve cores you need, whether you are replacing a single valve core or multiple cores for all your road bike tubes.
Installation: Valve cores can be installed using a valve core removal tool or a small adjustable wrench. Make sure you have the necessary tools and knowledge to install the valve cores properly.
Brand and Reviews: Consider purchasing from reputable brands or sellers and check customer reviews to gauge the quality and reliability of the valve cores.
Remember, if you are unsure about the compatibility or installation process, it is recommended to consult with a professional bike mechanic or a knowledgeable individual who can assist you in selecting and installing the correct valve cores for your road bike.

(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.
