5'7, inseam unsure to be honest. I know my saddle height/setback to the mm (72cm, 58mm setback to saddle tip based on a 280mm saddle - or 198mm to saddle centre point), it's the reach I struggle with on frames. I invariably end up with an 80/90m stem. I have an 80mm stem slammed on a ribble 7005 with a 53cm TT and it feels good.
Then the 50cm sounds good!
Was just curious - I normally think people ride frames that are too small, but with top tube and reach you're used to, the 50 sounds spot-on.
