Better Gravel Riding Starts with Shimano GRX

When preparing for gravel racing and adventure riding, you've always had to decide between pure road components or mountain bike components. There are drawbacks to both.

Shimano's GRX drivetrains excel in rugged terrain to keep you securely positioned on the hoods when the going gets tough. The gravel-specific design of the GRX shifter offers a more drastic slope on the hoods, with the tried and true light, mechanical shifting, you know and love from Shimano.

Better Control

To improve your grip and braking control, the GRX lever has a new, textured anti-slip surface.

The RX810 hydraulic calipers are effectively the same as Shimano's flat-mount road calipers, delivering a powerful braking performance of ServoWave, with heat-dissipating Ice Tech brake pads, as well as simple set up and maintenance thanks to One-Way Bleeding technology.

Features:

  • Greater mixed-terrain control
  • Same light shifting operation as top tier systems
  • Excellent heat dissipation
  • Flat mount
  • Convenient tool access
  • Simple wheel replacement
  • Easy and clean bleeding system
  • Never hesitate to tackle rough surfaces
  • Simple set up and maintenance
