The invention relates to a support structure of a wind turbine and to a method of manufacturing the support structure. A support structure 1 of a wind turbine is disclosed, whereby the support structure comprises a first end 2 to connect to a rotor of a wind turbine, and a second end 3 to be connected to a tower of a wind turbine. The support structure 1 comprises an intermediate part 4 that connects the first end 2 to the second end 3, and that the intermediate part 4 comprises the form of an elbow-shaped tube. The support structure 1 is divided into at least two segments 5, 6, whereby the segments are transportable individually from a manufacturing site to a construction site. The segments 5, 6 are connectable in a way that the support structure 1 is capable of transferring forces from the rotor to the tower.
