    Connection Type:vulcanization gelatinization joint (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.
