Its true for the pure cassette Birdy.
But the Pacific Cycles Touring uses a 3s Sturmey Archer hub with a cassette, this hub increase the longest gear inch.
And the Birdy Rohloff has also a longer gear inch than 52x11.
As already said, you will have a Birdy with a 9-32 cassette, the best is to use it and test yourself before changing the transmission.
