FWIW I prefer to put a water cage on the inside of the handlepost, preferably the Minoura or a Twofish. It's very convenient.
The bag has a draw chord which constricts the neck of a .75L bottle and holds it fast. Smaller bottles slip inside the bag completely and the draw chord covers them. They cannot fall out. I tried the water bottle on the inside of the handlepost but thought it spoiled the look of the Swift. I like the clean lines of the bike and prefer to keep the space between the seat post and the 'bar riser clear. Also putting the bottle cage on the inside of the post means that the cage will lean the wrong way with the possibility of the bottle bouncing out of the cage. On a conventional bike the bottle cage leans back on the frame and with most cages having a lower front than back, putting the cage on the rear of the 'bar riser (facing the rider) means that there is less material holding the bottle in place. I agree that putting the cage on the handlepost is more convenient but as I never drink while actually moving, placing the bottle behind the seat is of little consequence.
