I'm trying to size a bike for my teenage daughter as a birthday present. Your chart appears to be largely for the male figure, but any way, her sizes are: 5'2" tall, 29 3/4" inseam, size 8 1/2 ladies runner. Dividing height by 3.3 gives ~48cm (18 3/4") but I know thats way too big for her. I think something around 42 - 44 in a ladies fit might work, what do you think. She would be a recreational weekend rider.
