It goes without saying that if you want to be the best, you need to ride with the best, and nowhere was that more true than in last weekend’s 70.3 World Championships in Lahti, Finland: All of the top five women overall had top five bike splits (though fourth-place Emma Pallant-Browne shared her bike split with ninth-place overall finisher, Daniela Ryf); the same stat was true for the men. Today, it’s no longer possible to swim well, ride OK, run really fast, and expect to be on the podium.

With that in mind, we looked at the bikes that the men and women in the top five fastest cyclists rode at the 2023 70.3 World Championships. Of course the bike isn’t the thing that makes these men and women fast, but it’s worth knowing what these speedy triathletes were riding en route to a top-five bike split (and overall finish).
