The Pressure Rite Presta guarantees accurate tyre pressure every time. This anti-air loss connector is perfect for Presta valves on aerodynamic "disc" type track bike and time trial bike wheels.
Once you have connected this adaptor to your wheel's presta valve, you can then use any presta valve compatible pump on the other end of the adaptor.
This adaptor provides you with a presta valve connection at a more accessible angle for your pump's head.
Directions For Use:
1. When inflating tube, the pressure reading will rise quickly to the pressure inside the tube. Pressure will need to be increased until the check valve inside the Pressure-Rite device is opened. You will notice a
slight decrease in pressure when the check valve opens. When this occurs, your gauge will indicate the correct pressure reading. Pump to desired pressure
2. After desired inflation pressure is reached, disconnect pump head from the Pressure-Rite device first before you disconnect the Pressure-Rite device from the tube. If your pump has a pressure release
button, activate it to release pressure before disconnecting pump head from the Pressure-Rite device
3. Do not leave Pressure-Rite connected if it's not being used to inflate
