FCR2 Frame Too Small
Meredith,
First, let me begin by stating that even with a long torso your height puts you in the right category for a Small FCR. Of course, proper bike fit is not determined by height alone. A bike frame needs to be as close a reflection of your torso/arm and leg length proportions as possible.
If you push the seat too far back your change the relationship between the hip, knee, foot, and pedal, which may have a negative impact on pedal stroke efficiency. If the top tube is a little too short the better way to correct this is at the stem.
You are correct in thinking that a rounded back is an indicator of poor fit. But it may also be an indication of poor posture. When your hands rest on the bars, you should be able to draw your shoulder blades down the ribs to avoid hunching your shoulders; your spine should be lengthened and relaxed in neutral alignment (all curves present); your pelvis should be slightly tipped to allow the natural concave curve of the lumbar spine.
If you are willing to provide more information in regards to this dilemma, I would be happy to work with you on this further.
Take care, Meredith!
