Key Features of Individual Components

Shimano GRX ST-RX400 Shift & Brake Levers

The ergonomically shaped shift and brake levers offer comfortable handling for various handlebar shapes. Thanks to the non-slip coating, the grip remains secure even in changing conditions. Furthermore, the raised pivot point provides improved brake control, while the reach can be individually adjusted.

Shimano GRX BR-RX400 Disc Brake Caliper

The hydraulic disc brake caliper guarantees consistent braking performance on challenging terrain. Ice Tech technology efficiently dissipates heat, resulting in better braking performance. The Flat Mount attachment ensures compact integration on the frame or fork.

Shimano GRX FC-RX600-10 Crankset

This 2x10-speed crankset features an optimized chainline that provides more clearance for wider tires. The combination of 46 and 30 teeth provides a versatile gear range for various types of terrain. The 4-arm design of the aluminum chainrings is compatible with Shimano HG 10-speed chains. Shimano GRX FD-RX400 Front Derailleur With a 16-tooth capacity, the FD-RX400 harmonizes perfectly with the FC-RX600 crankset. Thanks to the extended chainline of the GRX series, wider tires can also be used without any problems. Its precise and smooth shifting mechanism ensures a natural shifting feel. Shimano GRX RD-RX400 Rear Derailleur This rear derailleur was specifically designed for gravel riding. The Shadow RD+ system minimizes chain slap and ensures stable, quiet shifting, even on rough terrain. An additional on/off switch locks the derailleur cage and reduces unwanted movement.
