The Shimano GRX ST-RX820 left dual control lever delivers light and responsive mechanical shifting for mixed-terrain riding and racing (Note: LD0374 is a non-shift dropper post remote variation for 1x set ups). The ergonomic shifter design improves comfort by decreasing pressure on your palms, while the textured, anti-slip brake lever surface increases control on bumpy terrain. The SERVO WAVE brake lever action provides greater braking power with improved control.
- 2x shifter with brake lever for use with GRX RX820 12-speed systems
- Gravel-specific lever body ergonomics and anti-slip lever coating provides greater control on mixed terrain
- Optimized for use with flared handlebars
- Reach Adjust mechanism allows the lever to be adjusted to suit any hand size, type of riding and individual rider preferences
- SERVO WAVE technoloy provides fast initial pad travel to quickly contact the rotors followed with the power multiplication factor to give fast pad-to-rim contact to apply greater braking power with improved control
