I used to use a roll of tape so that the saddle would go up to the correct length every time but now someone else uses the Brompton reasonably regularly so I can't do that. What are the suggestions for marking the seatpost so it's easy to get to the correct height each time? I've tried sharpies/permanent marker but that rubs off pretty quickly.
Dremmel or similar rotary tool. Get the seat at the right height, double double check, then engrave a little line on the post just above where the seat tube stops. Presto.... Get the sharpie on it then, and it should stay in the groove to make it a little more visable.
