Emsara, I forgot that your frame was quad-butted valite! Based on that, and the fact that the women's specific design fits you so well, making some further modifications is a sound investment (in your cycling pleasure.). Build your bike around shorter crank arms, a triple crankset and wide-range cassette, and higher bars, and you will be very pleased with the results!

What size frame is that? What is the standover height?

It's a very beautiful bike, in fantastic condition! You did very well for yourself! Congratulations!
