What to do with the white plastic tube in Dahon city vybe c7a? Just got a Dahon city vybe c7a:



It has a white plastic tube at the bottom, what should I do with it? It seems to prevent the seat pole from sliding down.
The seat clamp prevents the seat from sliding down. Not a plastic tube of any kind.

My hunch is that it's meant to be taken away. It's there only for some packaging purpose.
