I have a suspension seatpost and sprung seat that I took off from my 09 Fuji Crosstown 4.0 I would be willing to let go very cheap... I rode with it about 20 miles. I weigh in at 218 and can say that the suspension seatpost and sprung seat do their job. The seatpost suspension is adjustable as well as the springs on the seat. The only reason I took it off is because I swapped handlebars and could not get my seat height set right with the suspension seatpost. Anyway, pm me if your interested. (it is a 27.2mm seatpost).
