KOM, “King of Mountain”, this is the name of the most performance oriented and lightweight frame ever built by Kuota. The KOM represents 900 grams of the best technology and the most sophisticated materials available. Countless laboratory tests, stress simulations, impact analysis and CAD designs have produced this high performance racing machine. The KOM satisfies the UNI EN 14781 standards for strength and structural integrity.
Monocoque front triangle.
Differentiated lamination throughout.
Kuota NanoTechnology carbon fibres.
3K4H high impact weave.
Bottom Bracket with reinforced section.
Kuota Super Drive head tube 1-1/4”,
Shortened 402 mm reactive rear carriage.
What you can’t see in the pictures are the massive proportions of the Bottom Bracket or the oversized down tube. The KOM is incredibly deceptive. It looks exceptionally strong, and it is, but when you pick it up, its featherweight is almost unbelievable. The KOM rides like it looks - fast, stiff and precise. This is a pure stage race bicycle that is able to handle the cobbles, Cat 1 mountains and tight criterium corners like no other bicycle on the market. The KOM is the King of the Kuota Range.

In the all-new Madone, Trek Bicycle has taken its quest for perfection to new levels. Charged with creating the world’s finest all-day performance bicycle, an army of engineers, designers, physicists, chemists, carbon producers, bicycle shop owners, project managers and riders spent the past two years elevating the Trek Madone bicycle from elite racing cycle to the consummate performance experience. The result of their efforts is an exquisitely balanced machine that delivers a transcendental riding experience.
The new Trek Madone represents the largest design project Trek has undertaken on any bicycle, at any time. It was born from the expertise of seven consecutive Tour de France victories, more than 15 years of OCLV Carbon engineering experience and the input of Lance Armstrong and other world-class riders. The Madone underwent hours of FEA analysis, exhaustive real-world ride testing and 30 different lay-up schedules as Trek engineers fine-tuned every detail of this ultimate riding machine.
