Whether you are building up a new dream frameset or upgrading from 11-speed, this premium dual-control lever and caliper set offers crisp shifting, ergonomic comfort, and reliable braking performance in all weather conditions.
Key Features & BenefitsGravel-Specific Ergonomics: The ST-RX820 hoods feature an anti-slip texture and a revised hood shape optimized for flared gravel handlebars, reducing hand fatigue on long, bumpy rides.
ServoWave Action: The brake levers integrate Shimano’s ServoWave technology, providing rapid pad-to-rotor engagement and immense modulation, giving you absolute control on steep, loose descents.
Ice Technologies Heat Management: The included BR-RX820 flat-mount calipers feature finned resin pads to dissipate heat rapidly, preventing brake fade on long alpine descents.
