Tadej Pogacar breaks 3 Strava records during his reconnaissance for Paris-Roubaix 2025 including fastest time on Mons-en-Pévèle

Alsene, I tend to agree but it’s incredibly complicated to calculate who has what advantage in which particular situation as the variables are largely interrelated. As you note, the rolling resistance alone is affected by numerous criteria, all things equal it is easy to change one variable to determine whether the heavier or lighter rider has an advantage, however, when EVERY rider is free to play with ALL variables (tire pressure, bike stiffness, wheel seperation and dozens more), many of the advantages/disadvantages melt into a smaller overall a/d much harder to determine when there is not an enormous weight difference (we have riders from mid 50 - mid 90kg but most are much closer together). In the meantime each team has optimised the set-up for each rider so differences are nowhere near what they used to be 30-40 years ago but obviously there is and always will be some but without highly advanced scientific research (which no-one is likely to provide for free and investing teams will keep for themselves) I feel there is now little point in people like us trying to make any factor or point the determining one, none will ever outweigh the gains from drafting and strategy :-)
