Just a few months after the new Domane was spotted at Paris-Roubaix, another Trek road bike has shown up in the peloton. Today it was Madone's turn, as the new model was spotted at the Criterium du Dauphiné.

Ridden by select members of the Trek-Segafredo team, including Tom Skuzins, the bike stands out thanks to the wild joints between the top tube, seat tube, seat post, and seat stays. As the image shows, the seat tube splits in two and merges with the seat stays. The top tube continues further back to become a floating seat tube where the seat post fits. Trek's IsoSpeed technology seems to have been removed entirely, relying instead on the flex provided by this design.

Elsewhere, the overall tube shape is deeper, including a larger, deeper head tube and fork legs. The bottom bracket area also seems to have been strengthened, and the junction between the down tube and seat tube is much larger than before.

The Madone is Trek's fully aerodynamic bike, along with the endurance-focused Domane and the lightweight Emonda. In recent years, the industry has seen a fusion of aerodynamics and weight reduction, and the Emonda has received many aerodynamic improvements. Today's sightings leave little room for doubt: Trek is going all out on aerodynamics.

Images of the new bike are still sparse, but we will update this article as they become available.
