Shimano's study in the science of speed has taken developments to a completely new level. The freshly redesigned DURA-ACE groupset provides an abundance of evidence that Shimano will leave no stone unturned in the pursuit of next-level speed.
 
Wheel System: Aerodynamics, Rigidity, & Lightweight
The last pillar in the science of speed is the wheels, the final point between the rider's input and the speed output. Shimano has redesigned its wheel line-up with a balance of three factors: drag reduction without sacrificing control, driving force rigidity thanks to a new DIRECT ENGAGEMENT hub, and lighter weight construction. These principles make up a full carbon tubeless and tubular options to exceed today's standards.
 
C60: The Aero Alternative
The C60 is the aerodynamic choice of the R9270 range with a High Rigidity design for sprints and high-speed pursuits. It is focused on drag, lateral and driving rigidity benefits.
