I bought a new seatpost today. It is a Kcnc Pro Light 9000 31.6, length 400 mm. Only later I learned that it has a weight limit of 85 kg for xc use . If used on a full suspension bike will the suspension not absorb much of the stress placed on the components, especially the seatpost. The reason I bought it is because of its length and not to save weigth. Since I weigh more than 85 kg should I return it or hope for the best. Thanks in advance.
