The Chorus drivetrain provides precise and accurate shifting performance, buttery smooth gear transitions as you multi-shift across the cassette in one continuous sweep. This top-level gear performance is amplified by the highly-adjustable and powerful hydraulic modular braking system that provides instant and direct braking, meaning you can brake later when coming into corners, which enhances your overall race times.
