A rotor blade attachment assembly for use with a rotor hub to which a rotor blade assembly is connected includes a hub extender having an inboard end and an outboard end. The inboard end of the hub extender is configured to form a connection with the rotor hub. A blade fold axis about which the rotor blade rotates relative to the rotor hub is defined at the connection. An inboard bearing is mounted within an interior of the hub extender adjacent the inboard end and an outboard hearing is mounted within the interior of the hub extender adjacent the outboard end. A tension torsion strap is operably coupled to the inboard bearing and the outboard bearing.
