Dear Elisabeth, This is why stack and reach sizing helps cut through the mess that sloping top tubes and variable setback creates.
I turn out to be a bone-stock 56 cm racing bike rider based on the CONI manual, but that ends up being a: 57, a 55, or a 53 in Grant Petersen machines depending on the model, somewhere around a 59 in French-fit rando machines. It all works out to: 73 from the tip of my saddle to the top of the brake lever, 2" or so drop, and 73 saddle height with drop bars. Adjust for loop bars, add a pile of reach for mountain bike bars, and hope that nobody has cut the threadless steerer too short on non-gp machines. By the way, GP bikes were traditionally built with ling top tubes and slack seat tubes, contrary to the long-leg and short torso design orthodoxy for women. Individual variation trumps generalization, but stack and reach will help demystify the effective geo of sloping bikes. Or you can call in to the mothership. They won't steer you astray.
