Upgrade or repair your gravel setup with this genuine Shimano GRX hydraulic brake and shifter combo.

Specifically configured for Moto Style (Left Hand = Rear Brake), this set is standard for Australian riders.

This system features Shimano's J-Kit (Easy Hose Joint System).

The brake lever and caliper are pre-bled, and the hose is pre-installed at the caliper end.

This makes internal frame routing incredibly easy and saves you from a messy bleeding process upon installation.
