A new and unreleased Trek Madone aero bike has been spotted at the 2022 Critérium du Dauphiné.

The new Madone sticks with a similar aero silhouette to the previous bike but features a large cut-out beneath the seat cluster. This creates a hole where the top tube, seatstays and seat tube meet.

This cut out has, presumably, been added in the name of aiding rear-end compliance and reducing aerodynamic drag.

Notably, this cut-out doesn’t appear to be marketed as an ‘IsoSpeed’ system, according to road.cc . Trek’s signature frame technology sees the seat mast pivot on a bearing inside the top tube, allowing it to rotate more freely, increasing comfort.

IsoSpeed first debuted on the brand’s Domane endurance road bike in 2012. It was rolled out to the Madone in 2016 and, more recently, the Checkpoint gravel bike .

An integrated seat mast sits above the cut-out. This is similar in design to the current generation bike, with a narrow aero-profiled seat post sitting inside an extended seat tube.

The area around the bottom bracket has increased in size. This great big slab of carbon flows into the seat tube, which now hugs the profile of the rear wheel tightly.The top tube is no longer humped, following a straight path from the head tube back to the seat cluster.The integrated one-piece cockpit also looks to have been updated. This now features a slimmer profile that tapers into a more heavily sculpted clamping area. There is also a distinct ramp pointing down towards the top tube […]
