Teased as the "ultimate race bike" in the build-up to its release, Trek finally unveiled the new Madone at the Tour de France with several new features.
The most striking aspect of the design is a new IsoFlow seat tube technology that replaces the previous model's IsoSpeed system. The seat tube splits and forks outward to join the seat stays, resulting in an almost diamond-shape hole below the seat which screams out for attention.
So we took a closer look at Trek-Segafredo rider Mads Pedersen's new bike to get to grips with the new upgrades.
The IsoFlow system not only adds compliance for a smoother ride, says Trek, but also brings gains in aerodynamics and weight-saving.
In fact Trek says the new Madone is 60 seconds per hour faster than the previous generation thanks to its new aero frame alongside a redesigned integrated handlebar and stem. The hoods on the handlebar are 3cm narrower than the drops which Trek says allows for an improved, more aero rider position.
The new Madone will come with Bontrager's Aeolus RSL 51 carbon tubeless-ready wheelset, but Pedersen's bike was fitted with deeper 62mm rims in Copenhagen.
It was also equipped with SRAM's Red eTap AXS 12-speed groupset.

As well as cycling, his passions include podcasts, tennis and speaking enough Italian to get by on his snowboarding trips to the Dolomites. A DIY rider who is almost as happy in the toolbox as he is in the saddle, he is still trying to emulate the feelings he experienced as a nine-year-old on his first Peugeot racer – he couldn’t fathom the down-tube friction shifters then and he’s still wrestling with groupsets now. When he isn’t making a beeline for the nearest Chiltern hill, he is probably tinkering or teaching his kids how to clean a bike properly. He rides a heavily modified 1980 Peugeot PVN10 Super Competition (steel is real) when the road is smooth and dry, and a BMC Alpenchallenge when it’s not.
