My reply was based on the reasoning that as you reduce the rolling resistance of one component the relative proportions of other components to total rolling resistance increase.
The correct numbers are:
Brakes: 6%
Bearings and seals: 12%
Tires: 82%
Assuming 32 psi in the tires.
It is estimated that rolling resistance in a tire is reduced by 7% for every 0.3 bar pressure increase (~4.35 psi). Pump those tires to 45 psi and the rolling resistance is reduced by roughly 20%. The numbers now become:
Brakes: 7.5%
Bearings and seals: 15%
Tires: 77.5%
