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

Ok guys, both of you, this is far too complex to debate as a whole as there are dozens of variables and none of the conditions have been rigidly defined, what’s more, everyone is looking at things from a different angle and for a different purpose so let’s go back to the real basics first to see if we can agree on some starting principles. If you throw a golf ball or ping pong ball (assuming same size here) at the same speed in the same direction, which is going to land further? Ditto if you launch them with the same power? If two identical riders of 70 and 80kg (lets assume the extra 10kg is just bones and drinks and lunch) on identical bikes ride side by side at speed X with zero wind (or alternatively a really strong head wind) and both stop pedalling at the same time, which is going to roll further or come to a stop sooner? The wind force does inevitably come into play but I want to keep an open mind as to the effect it has in situ in practice because it obviously isn’t the only criteria and with acem82’s example it’s highly likely that wind is more minor but that wouldn’t be true for every real-life situation. Regarding cobbles, that’s an extremely complex motion to analyse, you can call it bouncing or hopping or climbing or what you like but in reality it’s indescribable and only high precision analysis can tell you exactly how much of each effect is contributing for each rider at each speed and every tire pressure/behaviour, you will NEVER manage to say that one criteria alone governs the whole efficiency equation.
