I'm not quite 5'2" , more 5' 1/2", hoping for a growth spurt! I ride a 48" Ruby Comp. It's by no means too small. I think I could probably ride a 44". I know others in our size range ride either the 44 or 48. Muirenn has given great advice on meeting at a bike store for fit and inspection. Seems like a great price if it fits and is in good shape.
