New Trek Madone breaks cover at Dauphiné… or is it an Emonda?

Lidl-Trek riders at the Critérium du Dauphiné are racing a new Trek road bike that retains the IsoFlow technology and the cantilever seatpost design of the existing model, but comes with shallower tubes, presumably to reduce weight.

Well, we're saying it's a new Madone because that's what it says on the top tube sticker and it's clearly an evolution of the seventh gen Madone that broke cover at the Dauphiné two years ago. There is a 'but', though. That top tube sticker might say 'Madone' but look carefully and you'll see that underneath it says 'Emonda'.

What's that all about then? Whatever it is, it's definitely a new top end race bike from Trek.

We first reported on this new bike at the start of the year, when pro rider Giulio Ciccone was spotted riding it at a training camp. At the time, we thought it was a revamped version of Trek’s lightweight Émonda, which is overdue an update.

Then, a new picture emerged a few days ago, leaked on the Weight Weenies forum.

Now Lidl-Trek riders are racing the new bike, which says Madone on the top tube, at the Dauphiné, which starts today in Saint-Pourçain-sur-Sioule, France – making it the eighth generation. Well, if you believe the sticker. Look closer at the shot below and you'll see there's another word underneath it.

We first spotted the seventh-generation Madone SLR here at the Dauphiné two years ago, although it wasn’t officially launched to the public until a month later.

The standout feature of that bike was its IsoFlow technology, which involves an interrupted seat tube. It’s one of those things that’s way easier to communicate via a picture than through words so…

Trek claims that IsoFlow provides dramatic aerodynamic improvements – it “smooths air as it moves over the bike and accelerates it through the frame for even more free speed”, according to the US brand – while reducing weight and adding compliance. The cantilever upper seat tube/seatpost design is intended to flex over bumps to smooth the ride.

Like most of the cycling world, we thought Trek would likely extend IsoFlow to its lightweight Émonda platform next. Why? Mainly because the Émonda hasn’t been updated in over three years whereas the Madone got its radical new shaping in 2022. However, it looks like we missed the mark there and Lidl-Trek’s bike is, in fact, the eighth-generation Madone.

Or is it? As mentioned, underneath that top tube sticker it says Emonda. There's a few possible reasons for that and we'll go into those later, but first let's take things at face value and assume we're dealing with a new Madone.

Although similar to the seventh-generation model (above) in some ways, particularly regarding the IsoFlow technology at the heart of things, the new bike features shallower tubes across the board. The head tube and down tube are far, far shallower than those of the seventh-gen Madone, and the same goes for the fork legs. 

The lower section of the seat tube wrapped around the leading edge of the front wheel on the previous Madone. That’s no longer a feature here – at least not to the same extent as previously – and the deep seatstays have been replaced by decidedly skinny ones.

What is Trek up to with this design? That’s harder to say because this new bike has yet to be launched and the company has released precisely zero information about it.

Over recent years, Trek has offered the Madone as its aero road bike and the Émonda as the lightweight alternative. However, several brands have moved away from that two-pronged attack (and some, like Pinarello, never went there in the first place). 

Specialized, for example, has been down the ‘one bike to rule them all’ route with its Tarmac SL7 and SL8 – bikes designed to be both lightweight and aero. It claimed a 56cm frame weight of just 685g in its lightest colourway, and a fork weight of 358g.

The seventh-generation Trek Madone SLR was launched with a frame weight of just under 1,000g, and a fork weight of just over 400g.

Trek clearly thought a little extra weight was a price worth paying for the aero gains, but we’d imagine that the tubes of the new Madone have been slimmed down to save grams. That’s speculation, of course, but it’s usually the way of things.

Will Trek have sacrificed aero performance to save weight? Who knows what it will claim when this bike is released? Trek will doubtless have a good story to tell and a white paper’s worth of justifications for the changes.

One final question: where does this leave the Émonda? One final answer: we don’t know. It could be that Trek is putting all its eggs into one basket with the Madone in the same way that Specialized has with its Tarmac, having shelved the aero Venge.

Maybe Trek is merging its lightweight tech and its aero tech into a single platform. 

Or maybe this actually is a new Émonda and Trek doesn't want pesky journalists spoiling an eve of Tour launch by finding the new bike first at the Dauphiné. I mean, it wouldn't be the first time that's happened.

We've been putting this story together, and all our other tech coverage from the Dauphiné, on the road in France and even as I've been writing this my thoughts on what this bike is have been changing. At para one I was fairly sure it was a new Madone, but by this point I'm thinking Émonda. It's a lot easier to put a name sticker on a bike than it is to put a name on under the clear coat and then slap a sticker on top of that. And if you are going to cover something up with a sticker, why not cover it up properly, eh?

Maybe it's an elaborate double bluff. Perhaps Trek will be merging the two platforms, or maybe it's part of a clever teaser campaign for a new Emonda? What we can say for certain is that whether it's a Madone, an Émonda, or both combined, it's definitely a new top end race bike from Trek.

Hopefully, everything will be revealed when Trek officially launches the eighth-generation Madone, or the (checks notes) fourth generation Émonda, although we don't know when that'll be. It's a good bet, though, that any new bike from a major brand that we see raced at this time of year will get a full release ahead of the Tour de France, and that's at the end of this month.
