Hello! I am looking at the Flaanimal 5.0 bike. I see the recommended heights for everything but the 49cm. I am 5’5” with 30 in inseam and shorter torso and reach. I am not an aggressive rider, preferring distance to speed on gravel. I sit up more like a tourer or an endurance rider. I am older too—just shy of 50.  I am on the border between sizes and wanted to know your recommendations. Thanks in advance.
