I couldnt find a quality pump that fit in the frame when i was looking and i had the Road Morph anyhow,so i didnt look to closely at factory one. I dont remember if i checked the factory one to see if it had the set up for the two different valve stems. Its been awhile since i checked it out.

I flipped the rubber ring and that small plastic tube of the stock Brompton pump and it seems to work with Presta valves, probably by design. The road is clear now to migrate to Presta tubes. I presume that Schwalbe SV4 is what I need.

1. Open the valve nut and remove the rubber seal and the plastic tube.
2. Flip the plastic tube and inset back in the pump
3. Flip the rubber seal and insert in the pump (it should seat nicely on the plastic tube).
4. Thread back the nut.

This pictures shows the plastic tube and rubber seal after flipping them for the Presta mode.

Looks exactly like the Road Morph set up, good to know. Might get one if it works good for you. Keep me posted Kamsta.
