\n\t\t\tHG-EV - The HG-EV Bike cassette sprocket is designed for rider-tuned gear combinations and cadence control. Shimano offers an optimal 11-speed drivetrain gear ratio; you can choose from a variety of wider and closer gear combinations to fit different riding disciplines. 11-speed gear is obtained with the HG-EV cassette sprocket without compromising 10-speed durability or improved HyperGlide shifting.
