Still getting to the bottom of this, he wasn't a fan of the 4S 51 either. I think an effective top tube closer to 53cm would be preferable for me. He moved the seat back 2cm and the shifters 3cm closer to the seat, so my hands were shifted back 5cm and down 2cm.
Going to try a stumpy 70mm stem and shorter reach bars to get through Winter and try to find an inspiring frame.
