So much happened in the race but I can't help thinking:
WvA had his usual share of mechanics (2 flats). So even though he won, he and his team should seriously look at his material / riding, because he always seem to have flats in Roubaix. Watching slo-mo footage going through corners, you see his (32mm Vittoria) tires are always very much into snake-bite territory, especially compared to Pog's 35mm front Conti S-TR. In any other scenario where MvdP and Pog didn't have so many race-defining mechanicals, he would probably have been on the backfoot like in previous years, and have had a much lower chance of winning the race.
But luck was (finally) just a bit more on his side and MvdP and Pog had bigger mishaps. But the biggest mishaps by the 2 main favorites was how they dealt with their mechanicals. There was a lack of sound decision-making and good team management both in case of Pog / UAE and MvdP / Alpecin.
In Pog's case, any DS would have designated all guys with approx. the same bike position as Pog to ride around him and don't move an inch away from him when he has a mishap. Pog was in a train of at least 3 other UAE riders when he flatted (notice he said he felt he had a slow flat in one of his tires and a big one in the other tire when he stopped, so not an option to change wheels or he had to change both), and none of the UAE gang stopped, not even 100 meters up on the road, to help him chase back or quickly switch bikes.
--> Pog should have had (ALL of) his team mates wait immediately, not just after 5 minutes / a lot of hesitation,... And he should have had a bike from a team mate, immediately. I'm not even going to talk about the amateurish way that Shimano car was on the left side of the road and the other car blocking off the path of other riders almost completely when Pog was stopping on the right, thus blocking the way for every other rider and their uncle.
In MvdP's / Alpecin's case, MvdP should have said 'no' to Philipsen's bike switch offer and tell him to keep riding and thus to wait further up the road (if he wasn't feeling his best). Even with the right pedals, riding on Philipsen's bike was always going to be a serious disadvantage for MvdP on Arenberg. He should always have resorted to Del Grosso for either a bike change or that front wheel change. The one clutch move in the team at that moment was by Del Grosso changing the front wheel for MvdP while he went for a leisurely walk in the forest.
It was the perfect storm that enabled WvA to ride the whole finale from Arenberg in the best possible position (not in the least thanks to the huge lead-out by Brennan into Arenberg, for once Visma got the positioning 100% right). He also handled his second puncture pretty well (his chase was slow but he was lucky with the asisstance from the Bora riders).
Ofcourse he was on a very good day as he re-took the initiative no more than 5K after chasing back to that front group, and from that moment on, when he followed probably the hardest acceleration of Pog (droppin gPedersen), he was riding in full control, and finished it off in great style.
some random observations:
There were quite a few crashes in Arenberg. I saw footage of Vermeersch who flatted his front tire, lost control and crashed in Arenberg. Such crashes would never have happened with tubulars, just saying.
Changing front / rear wheel like Del Grosso did is easy if you have that little hex. key with handle that's standard on many bikes these days (like Giant has it standard, Canyon also maybe)? It surely helps to quickly change a wheel with your team mate.
I can't help but think that neutral service is contraproductive. They often ride in the way of the race, can't seem to get the right wheel, or riders simply don't want / trust their wheels / bikes? I read the neutral service bikes have some set up identically for the top riders (so one set up for e.g. Pog, another for MvdP etc). Pog rode a Shimano bike with the same saddle height / reach / drop etc. So all in all that shouldn't have been that bad of a bike, but still, I always hear complaints about shimano wheels with tires at way too high pressure etc.
Christophe Roodhooft is obviously seriously annoyed with the pedal incompatibility issue in his team. I wonder if he even knew the cleats weren't compatible (you can have the knowledge about riders using a prototype pedal but you could assume cleats are compatible if you haven't tried changing bikes before). He also said that, for the first time, no guys with wheels were allowed half way Arenberg. I honestly don't understand why on the one place where you could really use a spare wheel, guys with wheels aren't allowed.
