Developed in collaboration with WorldTour athletes and professional triathletes, the Shimano Dura-Ace C50 WH-R9370-C50-TL Rear Wheel featured here at Escapa is designed to deliver peak performance through balance. By harmonizing weight, stiffness, and aerodynamics, it transforms the rider’s effort into efficient forward motion in real-world racing conditions. Agile acceleration, precise handling, and sustained speed work together to support every part of the Carrera. It hasn’t been optimized for a single metric, but balanced for what matters most.
From the earliest stages of design, testing by top-level cyclists guided the development to find the optimal balance between low weight, stiffness, and aerodynamic efficiency. In addition to the carbon spokes, the rim layout and thoroughly revised hub design deliver significant weight savings, achieving 709 grams for a more direct response on climbs and during acceleration. This design maintains reliable stiffness at professional-level speeds, providing stable handling during sprints and high-speed cornering. The new rim profile delivers high aerodynamic efficiency, maintaining speed across a wide range of conditions.
Features:
Rim depth: 50 mm
Designed for 28–30C tires: the 23 mm internal rim width reduces rolling resistance while preserving tire stiffness
Carbon spokes: The carbon spokes are optimized to balance low weight and stiffness.
Spoke pattern—Front 21 / Rear 21: combined with mixed-diameter carbon spokes to achieve low weight and stiffness for all-around use
Tubeless rim with holes: compatible with a wide variety of tires
Cone-and-cup bearings: excellent serviceability and precise adjustment to deliver speed and durability
Rear Wheel - DIRECT ENGAGEMENT: excellent drivetrain stiffness for maximum power transfer
