So at 56 aero spokes (F+R) the upper bound gain is 2.8W over round. Oh, not bad.
The lower bound is me slowing down at every junction cos stupid drivers which means I barely get to the upper bound :):)
Are there theoretical models or are such things pure measurement? Exp curve, scary Taylor series, how do they do it?

So how much W do you save per aero spoke over a normal spoke at 30km/h? :)
