🔗 The fastest site in the Tour de France

Which bike brand raced ahead in the browser as well as the bunch?

Today, the 112 th edition of the Tour de France came to a close. Wout van Aert won the final stage in Paris, and Tadej Pogačar, predictably, won the overall title, making it his fourth time taking the maillot jaune.

I’m a huge cycling nerd, and the Tour de France is the pinnacle of the sport. Three weeks of racing—21 stages—covering 3,338.8 kilometers of terrain, it really is a marathon and not a sprint.

But that isn’t to say that speed isn’t important! Cycling is a sport obsessed with aerodynamics, weight savings, and marginal gains. Bike manufacturers obsess over every gram shaved or watt saved. Cycling is the perfect sport for the performance engineer because things can always be measured, and they can always be improved.

And while most of the success undoubtedly lies on the shoulders of the athletes, as a bike manufacturer, having the lightest or fastest bike puts you in a much stronger position on race day. And indeed, this leads to some fairly outlandish statements:

Nothing is faster than the Tarmac SL8 […] it’s more than the fastest Tarmac ever – it’s the world’s fastest race bike.

— Specialized

Or:

Having a leading high-tech wind tunnel on-site, unique for a cycling brand, enables us to build the fastest bikes in the world.

— Ridley

Bold claims, but how do they stack up in the browser? For an industry utterly obsessed with speed, how does that translate to its online presence? Every individual in the peloton wants to be the fastest rider, and every bike manufacturer that sponsors them claims to have the fastest bike, but who has the fastest website?

I took a look at the sites of every bike manufacturer that has a presence in 2025’s Tour (all 21 of them) and ran the numbers. My question: does a bike brand’s focus on web performance predict their performance on race day?

The results are in…
