The fresh 2, 5, 6 and 7 series of Trek's Madone road bikes feature a so-called KVF frame tube shape, which is designed to keep the frame stiffness high but increase the wind resistance even further compared to the 2012 Madone series. The fork also has this new tube shape. Trek even compares these good properties in the airstream of the top model with a plus of 25 watts in the drive at 40 km/h riding speed in a light headwind.

Fresh look on the rear triangle
The Direct-Mount Shimano brakes, which offer less surface area for the wind to attack, also blow into the same horn. On the fork, the brake fits snugly against the crown. And on the rear triangle, Trek has even dispensed with a brake bridge between the seat stays and transplanted the rear brake under the bottom bracket.

Slimmed down
The 7-series has slimmed down the frame weight considerably, with these frames weighing a mere 750 grams. This corresponds to a weight reduction of up to 200 grams compared to the predecessors and the manufacturer promises good stiffness values despite all the lightweight construction.

Wind-slip for everyone
For the 5, 6 and 7 series, Trek packs its expertise in the processing of carbon fibers into the frames. In addition to these so-called OCLV versions, the Americans are sending an aluminum version of the 2 Series Madone onto the roads. Thanks to the equally aerodynamically designed frame tubes, this metal model is also intended to trim athletes on a tighter budget to a streamlined look.
