I realize that I need to be "fitted" for a new bike, but my current bike is literally on it's last leg and I need a new one fast. I am looking to get the Giant OCR A1 women's specific. I have been calling shops in my area (to see if they have any in stock) that are Giant dealers but I'm not sure of my size since the women's compact sizing differs from the men's. Someone told me I was a 50cm because I am just under 5'4". That would make me a size medium on the women's giant. If that's the case, that seems awfully weird that Giant would only make this specific model of bike for women 5'4" and under (they only list XS, S, and M as size options). What am I doing wrong here? haha
