Good morning ya'll. I am a male rider, who has been asked by my fiance (also a rider) to get a used bike for a friend of hers who wants to start riding. I have little knowledge of bike frame sizes for females her size. I asked a few of the female racers who I ride with from time to time, and they recommended a 48cm top tube.

The girl is 5'4" with a 29.5" cycling inseam. Can any of you who are this size or have experience fitting this size give me a frame size to look for?

Thanks for any and all help!
