A shroud for a rotor assembly is provided comprising a mounting ring, an aft seal ring, a forward seal ring, and a blade outer air seal. The mounting ring is fixed within the casing surrounding the rotor assembly, and includes a first attachment apparatus. The blade outer air seal includes a plurality of body segments. Each body segment includes a first face, a second face, a plurality of passages for receiving cooling air disposed between the faces, a second attachment apparatus, and a post for biasing each the body segment in contact with the aft seal ring. The first and second attachment apparatus cooperate to suspend the blade outer seal segments in close proximity to the rotor assembly.
