@bike8usa - Go to the Swift thread here and you will see a Thudbuster on a Swift. As far as I know I was the first person to mount a Thudbuster on a Swift. I have a Brooks Pro seat mounted on it. I also have Big Apple tires on my Swift which everyone said wasn't possible.

The way to mount the Thudbuster is get a Dahon telescopic seatpost and remove the top part of it. Get a standard 27.2mm Thudbuster and it drops it. Another option is to buy the Dahon specific Thudbuster post but that costs more money.

Hope that helps.
