With any bike development, you have to make decisions. Do you opt for the standard? Or dare to innovate? When designing the Kanzo Fast, we were faced with this very crucial decision. Do we configure the seat tube for a front derailleur, thereby reducing possible tire width and aerodynamics? Or do we ditch the front derailleur? With the development of 12-speed and 13-speed groupsets, and new technology such as Classified, we were able to successfully do away with the front derailleur.

Since we no longer had to consider dual chainrings, we could design the chainstays to our liking, while still having plenty of room for 42mm tires. As proven by extensive wind tunnel testing, removing the front derailleur also had a major effect on aerodynamics.
