More Insights and Trends From the Men's 2025 IRONMAN World Championship Bike Count

Originally published at: More Insights and Trends From the Men’s 2025 IRONMAN World Championship Bike Count - Slowtwitch News

The bike count from the final full distance IRONMAN World Championship in Nice is done and dusted. As we announced earlier in the week, Canyon led the way for the third consecutive count, with more than 20% of the field riding a Canyon bike. That being said, though, we wanted to break down some of these numbers a bit further — and pull out some surprising trends that the numbers alone may not have shown.

On Bikes: Canyon Gobbles Up More Market Share, and QR Makes Inroads in Europe

Canyon crept over the 500 bike threshold this year in Nice, with precisely 20 more bikes being racked versus last year’s Kona. You can almost directly tie that to the decline in bikes that Cervelo saw from last year to this year; there were 33 fewer Cervelo’s in Nice.

Giant had a big year, going from 60 bikes in 2024 to 95 this year. The launch of the next generation Trinity, along with strong at-once availability, seemed to certainly be of benefit. It, of course, was also ridden to great effect by Gustav Iden on his way to a second-place performance. Cube also put up a 60% increase in bikes going from Hawaii to France — it’ll be interesting to monitor these brands counts over the change back to a single-day world championship in Kona.

Perhaps most surprising is the performance of Quintana Roo, which gained a couple of bikes versus Kona 2024. It was not until recently that Quintana Roo offered direct sales within Europe. The recent X-PR, V-PR, and V-PRi bikes were all well represented in the field.

Specialized continues its downward trend in the bike count, having effectively called time-out on its triathlon offerings. You can’t, today, order a complete bike for triathlon racing from Specialized. You can order the extremely long-in-the-tooth Shiv Tri module (complete with rim brakes, no less!) for $4,500, or you can purchase the Shiv TT module for just over $6,000. A far cry from 14 years ago, when it took out ads proclaiming the speeds Craig Alexander used the new Shiv Tri to win that year’s IRONMAN World Championship. Felt, too, continues to trend downward, down 27% year-over-year.

All of the most non-traditional frame shapes saw drops in their counts. CADEX, KU, Ventum, and Dimond all slide in the count. That may be in part due to the course, as 13.35% of the field opted for a road bike for the significant climbing the Nice course contains.

Here, we break down the changes year-over-year from this year’s count compared to last year’s men’s race in Kona.

Wheels are Becoming More Regional

In perhaps the biggest shock of the bike count, DT Swiss took the overall top spot in the wheel count. DT Swiss accounted for 505 wheel sets, or roughly 20% of the registered field for the race. It beat out long-time leader in the category Zipp by 95 wheel sets.

I am sure that our Reader Forum, based on our recent discussions on hookless, would point to Zipp’s move to the technology as the primary reasoning. I say not so fast. There’s a fair number of factors in play here. Don’t get me wrong: I am sure that for a few purchasers, hookless may have been a consideration. But considering our recent polling on this issue — where the majority of purchasers don’t have a clue as to whether their wheel set is hooked or hookless — there are other factors likely at play.

1.) DT Swiss has become a stronger OEM player. Canyon, in particular, has featured DT Swiss as an OEM-spec option for multiple years now. Given the brand’s continued dominance in the bike count, it’s unsurprising to see gains in the count.

2.) Tariffs work both ways. Much has been written about how President Trump’s tariffs are impacting imported bike pricing here in the United States. Reciprocal tariffs, however, mean that US products within the Euro zone have also suffered from price increases. Despite the recent agreements that see US products imported to Europe subjected to lower fees as compared to European exports to the US, the pricing dynamic can’t be ignored.

3.) Kona data indicated regional bias. Zipp had 561 wheel sets on the Kona pier last October when the men took to the course. You simply don’t lose 151 wheel sets overnight. If I had to assign percentages to this, I’d put 100 of those athletes who are regionally biased on their purchasing behavior; 30 of those athletes who procured new bikes and bought OEM-spec wheels; and maybe 20 of them who decided hookless was not for them (the Slowtwitch Forum crowd is strongest at this event). Mind you, this is also despite many pro men declaring tire pressures well below 72 PSI (as we’ve seen with both Kristian Blummenfelt and Matthew Marquardt’s pre-race galleries)…but that’s another story for another day.

Other tidbits of note: we counted less than 25% of bikes racked as having a rear disc wheel. Apparently, Cervelo’s memo on always running the disc did not make it to the age group field. And almost 17% of the field were on rim braked wheel sets. That’s a bold strategy, Cotton, on this bike course…

Shimano Has Won The Groupset War

For a long time, it looked like SRAM was going to make in-roads on components. At the very least, SRAM’s mechanical gear-shifting outclassed Shimano’s by a wide margin. In my opinion, the greatest mechanical triathlon groupset was SRAM Force 10-speed with the TT900 shifter. But I digress.

SRAM has solidly captured about 30% of the triathlon marketshare. Whether in Nice or in Kona, there’s around 700 to 725 bikes that will have SRAM components on board. It’s not bad. The problem, of course, is that Shimano more than doubles that marketshare — whether in Hawaii or in Nice. There were 1,600 bikes with Shimano in Kona last year. There were 1,600+ bikes in Nice with Shimano drivetrain components this year.

This despite SRAM being first to 12-speed, and being the leader in 1X drivetrains. It’s Shimano’s world, and we’re all just playing in it.

The only one I couldn’t imagine was the Airsteem - and then I realized this was Deja Vu all over again

Also, curious about the Liv and why that might have been ridden vs the Trinity?

They must have just liked the color :slight_smile:

I could totally see that! I’ve always preferred the Liv color offerings!

You can’t run a disc wheel in Kona. How much of this is just people in Kona riding their other set of wheels vs running a proper race wheel + disc combo in Nice?

Geezus, the lengths you go to fall over yourselves defending hookless is mind boggling. The ONLY reason there is ANY hookless at all is because the poor schmucks got them forced as part of a Sram package.

I’m still yet to hear of anyone who knowingly handed over cold hard cash to purchase a set of hookless-if anyone is out there please let me know…

Again – this is likely to be region bias. DT Swiss has significantly upped their own OEM packaging, particularly in Europe (look at the number of brands impacted by their recent recall).

So I don’t think “race wheel” choice has much to do with it. Just where people are buying their bikes from.

Frankly, the comment over hookless was simply to preclude the “look! the market has decided! hookless is failing!” argument.

If we see huge growth in DT Swiss count over this year’s Kona and next year’s combined field, then we’ve got a different argument to have.

You sound so crazy in this reply… to say that no one is buying ZIPP, ENVE, CADEX, SYNCROS, HUNT and others just because you choose to hate a technology. Get over it dude… millions of people are on these wheels… MILLIONS. You’re literarily saying that ALL of them bought those as a “Package” ? Come on…

The vast majority. I still haven’t come across a single person who knowingly purchased them. I’d expect we could hopefully find one here…still waiting.

What was the zipp count and DTSwiss count at 2023 Nice? That seems like a better comparison than to Kona 2024.

DT Swiss 725 20.42%
Zipp 530 14.93%

Thanks. And that’s what I thought. I do agree that it’s more of a regional thing with DTSwiss. Are zipp losing customers? I think so but it’s a variety of reasons. Some of that is hookless (although small), some of it is OEM specs of non zipp wheels, pricing, and there’s more wheel options than ever before.

Kona data will be interesting this year. And next years too.

I think that Zipp‘s decreasing share has everything to do with hookless and the quoted poll that people have no clue whether their rims are hookless or not kinda underlines the point: With hookless, you need to know that you are riding hookless and stick to the approved tires and pressure. Now image you are with Canyon or another big brand and you spec the factory wheels: would you spec a hookless set and risk the bad press from your customer putting on unapproved tires with 7 bar? I wouldn’t. Of course there are still Canyon‘s with hookless rims being sold but manufacturers need to diversify and there are supply chain constraints. Nevertheless, supplying hookless rims with a complete bike is just an added risk not worth taking.

“Mind you, this is also despite many pro men declaring tire pressures well below 72 PSI (as we’ve seen with both Kristian Blummenfelt and Matthew Marquardt’s pre-race galleries)…but that’s another story for another day.”

Go back to your pre-race article. You wrote Marquardt was above 72PSI.

If he’s like me it’s because he’s paranoid about tubeless air loss and fills them to 75 first thing in the morning thinking there’s a decent chance that 5 hours from now they’ll be down to 72 anyway.

We’re not including gravel right. Otherwise I know a few who bought the mega wide Zipp ones.

Zipp has also lost a lot of their brand appeal, hype, glory over the last several years. They used to be the gold standard. Their 858 rim brake and first iteration of 858 disc brake wheels did not test well in the wind tunnel (their newer wider and hookless wheels apparently have tested better). Their super 9 disc disc brake wheel was a rim brake wheel with a disc brake axle slapped on it for several years until they finally came out with a true disc brake wheel a year or 2 ago. There are many competitors out there that make just as good wheels, likely better and faster, at a better price point. That didn’t exist 10ish years ago. Not to mention they used to have all the top athletes riding their wheels: Macca, Kienle, Frodeno, etc. I’m not even sure who their flagship athletes are anymore besides Paula.

I’m specifically referring to the tri market. I do think they’ve done well in gravel and off road. But perhaps that’s where their focus is on and less so on triathlon.

This coming from someone who has owned zipps since 2011 (808 non fc, 808 fc, 858nsw rim & disc, super 9 rim & disc, 404 nsw rim brake which I still have).

Except bear in mind 75 at 6am will be 78+ by the noon descent. What’s the rim limit?

This site is becoming a mess of misinformation and lies..all in the name of a (as of today) inferior wheel technology they seem obsessed to push it to the masses. It’s kind of sad.
