Road Bicycle KTM Revelator Alto Prime – Carbon | Shimano Ultegra Di2 12-Speed
Next Chapter. Leave the Valley Behind.
The KTM Revelator Alto Prime represents the pinnacle of the KTM road range: a racing bike in premium carbon, developed thanks to experience gained in the most demanding professional competitions, including the Tour de France.
The Revelator Alto project was born from direct feedback from KTM professional teams and extreme tests carried out on the toughest routes in the world. The pre-series prototypes were tested on the legendary cobblestones of the Paris-Roubaix, while the aerodynamics were optimized in the wind tunnel. The result is a frame capable of combining excellent climbing qualities with a very low aerodynamic resistance, ensuring complete performance in every race scenario.
The Revelator Alto Premium Carbon frame has passed the most severe testing period in KTM history and is the same used by professionals in World Tour competitions. Not by chance, already on the first outing with the new ALTO, the Frenchman Pierre Rolland won the best climber jersey at the Critérium du Dauphiné.
The Prime version is equipped with the electronic transmission Shimano Ultegra Di2 2x12 speed, carbon wheels Mavic Cosmic SL45, integrated FSA cockpit and top-level components, to offer a race-ready bike that is light, responsive and precise.

A Complete Guide to Bike Sizes
Foreword: Not all bike sizes are the same
Each type of bike has a specific frame and often uses a different size scale. For example, a road bike with a 54cm frame might be considered a medium size by one brand, but a large by another.
Bicycle adjustment margins
Some types of bikes, like gravel bikes, offer a wide range of adjustments, adapting to different body types. Other models, however, have limitations in this regard. This is an important aspect to consider.
