Shimano R9270-C50 DURA-ACE 50mm Clincher CL Rear Wheel (Shimano Micro Spline)

DURA-ACE R9200: Built without compromise
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.

C50: The All-Rounder
The C50 is the all-rounder of the R9270 range, with a great balance of drag, lateral and driving rigidity, periphery and overall weight and controllability.
