That's my old set-up with UCI-legal seat post, 60mm risers, silicone rubber top tube protector and uncut steerer. Swapping to the illegal seatpost, 55mm risers, helicopter tape aerofoil top tube protector and trimming 20mm off the steerer has cleaned up the airflow approximately elebenty gazillion percent.

Did some complex aero testing using computer modelling and real life wind tunnel experiments, thanks to a friend who works in the field. I have got him to represent the data findings in a graphic. Have also included @mdcc_tester T3 for comparison. The results were both pleasing and astounding.
