Schrader Valve By Sureka Marketing

Schrader valves are familiar to those who operate automobiles. They are common on mountain and urban bikes. We typically replace the Dunlop valves that come standard on Kalkhoff bikes with Schrader upon request, or when needed.

To inflate a Schrader valve,

Remove the black plastic cap covering the valve. If there isn't one, ask us for a replacement next time you visit.
Use a Schrader capable pump or compressor and press or thread it on to the valve.
Inflate to your desired pressure, within the limits specified on the tire sidewall.
Remove the pump and thread the black plastic cap back on the valve.
