Built around the class-leading Shimano Dura-Ace Di2 groupset and equipped with DT SWISS ARC 1600 carbon wheels, the REACTO PRO with CF5 frame brings together all the essential ingredients for a top-level road bike. Thanks to the changes we introduced to the Generation V frame, the PRO version sets new standards with its impressive ability to slice through the air and its reduced weight, as well as its improved ride comfort — particularly noticeable on rougher road surfaces.
