USE Seat Clamp Kit - Sumo

Called the Sumo this post uses a single bolt with a couple of cones mounted on a cylinder at the top of the post. The point being that the single bolt holds everything together but since the cones take all the load forces the bolt experiences no shear forces and is used only in compression.

What does this mean? Well, since all the force of the rider's weight is spread out over the surface of the two large cones and not through the bolt, the post should stand up to a lot more clumsy punishment than previous USE seatposts - hence the 'Sumo' name.
