It’s a half baked argument, and that’s being polite.
I will concede that it seems plausible that any specific country’s interest in a sport may wax and wane to some extent with the prominence of compatriots at the highest level of said sport. The spike in American interest in the Tour de France in an era when no-one won is fairly compelling. Google trends shows similar in the UK in the Team Sky era of Froome, Wiggins etc.
However, that’s where the argument ends. The author really fails to make any further points.
The author states cycling has a “problem” that, by insinuation, tennis doesn’t. It’s unclear what this problem is, or what metric the author is using to measure the success of a sport. It’s also odd to just consider two sports (cycling versus tennis), when any number of sports could be considered.
By pretty much any metric, cycling is a far more popular sport worldwide than tennis.
In terms of TV viewership, most statistics put cycling far ahead of tennis. One website claims 3.5 billion people watched the Tour de France, versus 25.6 million for Wimbledon ( The 15 Most Watched Sport Events (2025) ). I’m a bit suspicious of those numbers, but numerous sources put Tour de France viewership in the hundreds of millions, versus tens of millions for tennis.
In England at least, far more adults participate in cycling recreationally than in tennis: https://researchbriefings.files.parliament.uk/documents/CBP-8181/CBP-8181.pdf
Globally, the cycling industry is worth roughly USD 70 billion, versus around USD 5 billion for tennis: Bicycle Market Size, Share & Trends | Industry Report, 2030 Vs Tennis Market Size, Industry, Share, Demand, Growth -2032
All this would seem to seriously undermine the author’s argument that tennis is somehow doing better than cycling.
I would note that the author’s bar charts are simply batshit crazy - why on earth would you stack a country twice because two people from that country are in the top ten? The population a country doesn’t magically double…
Maybe, maybe, there would be a nugget of truth if the argument was:
The cycling industry is dependent on amateurs buying cycling equipment for their own recreational use. America, being a wealthy country, is disproportionately important to the global cycling market. American interest in cycling would be higher if there were more Americans amongst the top ranked cyclists. This would therefore help reduce the financial problems that some companies within the bicycle industry are currently facing.
But, of course, that is not the argument put forward.
