great ride, well done, fantastic analysis; the interesting thing about drop bars off road is yes you have an aero gain, however the real aero gain/energy saving is drafting others vs just being in the wind in a lower position with the drop bar, I'm sure being behind others is the ideal and has greater aero gains. Now the bigger issue for me is the loss of leverage the wider bar offers (and ability to unweight), picking lines on high speed descents etc, and maybe that's why k punctured. Just a thought from my experience mtb and cx racing.
