This is the third of six articles in which Paul de Vivie considers the ‘enemies’ of the cyclist.
The title line includes the expression: P(0.01+p)+0.003V2. ‘P’ is the all up weight of bicycle and rider, ‘p’ is the gradient and ‘V’ is the velocity. The first part of the formula represents something to do with rolling resistance and gravity, the second part of the formula is concerned with air resistance.
The particular ‘enemy’ that this article focusses on is weight (which was also discussed in the second article). Weight of the bicycle, weight of the rider and weight of your luggage - so many enemies.
