PRODUCT DETAILS

The Shimano GRX ST-RX610 dual control lever delivers light and responsive shifting for mixed-terrain riding. The textured hood and anti-slip brake lever surface increase control on bumpy terrain. The RX610 shift/brake lever is paired with a GRX BR-RX410 flat mount disc brake caliper that brings a new level of control to gravel cycling with enhanced modulation and a quicker initial braking point. And despite its compact construction, the system is quieter and easier to maintain.

  • 2x shifter with brake lever for use with GRX RX610 12-speed systems
  • Gravel-specific lever body ergonomics and anti-slip lever coating provides greater control on mixed terrain
  • Reach Adjust mechanism allows the lever to be adjusted to suit any hand size, type of riding and individual rider preferences
  • GRX BR-RX410 flat mount 2-piston brake caliper has 10% wider pad clearance to decrease brake noise
  • Includes L05A-RF pads with finned backplate and resin compound for enhanced heat dissipation
  • One Way bleeding makes cleaning and bleeding the system easy
  • Disc brake rotor sold separately
