Shimano GRX Brake Set for Gravel Bikes.

This is a set with an STI grip on the left side.

The grip is an ST-RX600 and the brake caliper is a BR-RX400.

Installed with a buckle clamp system.

Suitable for gravel, the grip comes with an anti-slip coating and is ergonomically shaped, which makes the grip good on uneven ground.

The brake caliper is to be installed with flat-mount mounting.
