Susanoo requires double Mangekyo.

You need Tsukyomi and Amaterasu to make basic Susanoo without legs. But the lower half of Sasuke's Susanoo is generated by Itachi's Susanoo (Madara's Susanoo is generated by Izuna's Susanoo). But the special ones with the long noses are created by the Rinnegan.

You don't need Rinnegan for a perfect Susanoo. When facing the 5 Kage Madara stated his perfect Susanoo rivals the power of a tailed beast. I would imagine he knew this from expierience fighting Hashirama. At this period of time he had not obtained the rinnegan but still had perfect susanoo. He actually obtained the rinnegan right before the end of his life when he was immobile so he wouldn't have had the chance to test it on an opponent. This leads me to believe that the Rinnegan has nothing to do with his Perfect Susanoo.
