Yes, this set includes a flat-mount disc brake caliper, requiring a compatible frame designed for flat-mount brake installations. It also requires a frame compatible with Di2 internal or external wiring.
The kit contains a bled right-hand ST-RX715 STI lever, a BR-RX410 flat mount front brake caliper with pads, SM-BH90 hose, and mineral oil. Rotors and adapters are not included.
No, this is a Di2 electronic shifting system and is not compatible with mechanical shifters or derailleurs.
Brake bleeding frequency depends on usage and conditions. A good practice is to check annually or if you notice a decrease in braking performance or a spongy lever feel.
This Shimano GRX hydraulic disc brake system uses only Shimano mineral oil. Do not use DOT fluid, as it can damage the system.
It is generally compatible with other Shimano 12-speed Di2 road and gravel components. For optimal performance and compatibility, it's best to use it with other GRX Di2 derailleurs and components, and ensure all wiring is using the correct EW-SD300 specification.
The brake system may need to be bled. Ensure you are using Shimano mineral oil and follow the correct bleeding procedure. Check for any leaks in the hydraulic hose or at the caliper/lever connections.
Check all Di2 wire connections for security and cleanliness. Ensure the Di2 battery is sufficiently charged. Connect to Shimano's E-TUBE app to diagnose potential errors or update firmware.
Inspect the lever mechanism for debris or damage. Ensure the hydraulic hose is not kinked or binding. Check for proper alignment of the caliper on the mount.
Verify that the brake system has been properly bled and filled with mineral oil. Check that the brake pads are correctly installed and making contact with the rotor. Ensure the caliper is aligned correctly over the rotor.
