Product Description
The all-rounder of the new DURA-ACE wheel lineup, the C50 is both lighter than the previous C40 model and nearly as aerodynamic as the previous C60. It's a wheelset at home in a wide range of conditions. From time trials to criteriums, on rolling terrain or attempting a personal best, the new C50 is the ideal wheel for spirited road riding.The perfect blend of low weight and aerodynamic performance, the all-new DURA-ACE C50 features an updated all-carbon tubeless rim and a new hub design that drops weight while enhancing rigidity.Key Features:Lightweight tubular full carbon 50 mm deep rim for improved aerodynamics, increased rigidity and excellent inertia for sprinters and TT specialistsEasy to use Center Lock rotor mount for use with disc brakesStainless steel butted (2.0-1.8-2.0) and bladed straight pull spokes for optimal balance and rigidityElbow-less spokes make for a strong yet compliant wheelHigh lateral rigidity is produced with a wide flange spacingLabyrinth double-contact sealing effectively shuts out water and dirtAlloy cone with integrated steel Borozon treated bearing races - super mirror finish reduces frictionCold forged, machined aluminium hub shell and oversized 7075 alloy axle keep the wheel weight to a minimumFor 100 x 12 mm axleTechnologiesCenter LockThe CENTER LOCK system makes an easy rotor installation possible with a spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time for both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.D2Aerodynamic performance is affected by wind direction. To create the D2 rim, SHIMANO engineers considered both frontal and crosswinds, aiming to achieve optimal performance in real-world riding conditions. Extensive prototype testing, in the wind tunnel and on the road, proved that a wide rim shape with a deep tyre bed performs best across a wide range of conditions. At yaw angles ranging from 0 to 15 degrees, the SHIMANO D2 rim profile reduces air drag better than other aero-shaped rims. This rim design also boosts lateral wheel stiffness and offers improved vertical compliance for increased control, comfort and durability on the road.E-ThruThe tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15 mm thru-axle system is 15% stiffer torsionally and 25% stiffer in transverse shear than a traditional 9 mm quick-release front axle system. High rigidity is secured while keeping the optimum weight balance. The E-THRU axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed.
