Shimano WH-R9270-C50-TL Dura-Ace Center Lock Disc Carbon Front Wheel

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 new hub design that drops weight while enhancing rigidity.

E-THRU

The tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15mm 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.
