At normal speeds, rolling resistance is large WRT wind resistance...

RR is, for the most part, constant while in motion, but lets explore the differences with respect to each other.
Here's a measured number that's pretty close to accurate (
Here's where I'm getting my numbers from.
RR= CRF*Normal
AeroR=.5*(rho)*v*v*cD*A
RR=.0106*1000(kg)*9.81(m/s^2) = 103.986(kg*m/s^2)
AeroR=.5*1.2(kg/m^3)*v*v*.370*2.3(m^2)
So...
103.986(kg*m/s^2)=.5*1.22(kg/m^3)*v*v*.370*2.3(m^2)
therefore
v= 14.1533 m/s
or 31.66mph
That is, RR dominates until 31  but that doesn't mean AeroR doesn't play a role until then. 103N = 23lbf
So lets say we're going 40 (perfectly reasonable, normal speed).
That 165.98 N = 37.31 lbf
@55 (gassaver's highway speed
)
313.81N=70.549lbf
@70 (Highway speed limit for most of everyone else  as if people went that slow :/)
508.33N=114.27lbf
From 3155... Not even doubling our speed  we more than triple the aeroR. From 3170  A speed increase of ~2.25X, we nearly
quintuple our aeroR.
All within normal driving speeds  really most cars live between 0 and 80. We could say people on here don't drive that fast... But unfortunately, we're not a good sample of the driving populace :/
This is why aero is such a big deal and what allows a bike to go 81mph under human power o.0
