My Presta to Schrader adaptor is installed permanently as a dust cap.

Surplus rotating weight!

Many pumps nowadays have interchangeable heads. If you unscrew the end cap you will often find that the rubber seals reverse to accept Schraeder/Presta.

Yes, the Brompton one does that, it's built for them by Zefal.
