Using our validated model of the power requirements of cycling (1) and assuming:
1) total (i.e., cyclist + bicycle) mass = 85 kg,
2) coefficient of rolling resistance = 0.004,
3) drivetrain efficiency = 97.5%,
4) air density = 1.185 g/L,
5) CdA = 0.225 m2, and
6) power = 300 W
I calculate that using an Omega instead of a Simkins would save you 1.9 s in a 40 km TT.
With the same assumptions as #1-4 above and assuming:
5) CdA =0.250 m2, and
6) power = 225 W
I calculate that using an Omega instead of a Simkins would save you 7.9 s in a 180 km Ironman bike segment.
