Kudos…you need the right idea at the right time and we have a next David Tinker here (intervals.icu).
Your cervelo model above has 2 front cables. Could you remove those cables in the model and show us the difference in cda or watts saved at 30 km/h for example. Could you also do that for 4 cables vs 2 cables vs 0 cables?
That would be very interesting.
