Shimano GRX FD-RX820-F front derailleur, 2x12, braze-on
Gravel cycling has its roots in simplicity, inclusivity, and curiosity. Everyone, from beginners to seasoned veterans, relies on Shimano GRX, the first gravel-specific groupset - for smooth shifting, reliable braking, and exceptional off-road comfort.
Shimano GRX stands apart from the rest of the Shimano parts world, and the new RX820 series offers premium performance at an incredible price, with thoughtful ergonomic design and gearing focused on gravel roads.
This is not a reworked set of road components. It represents a fundamental perspective on how cyclists want to discover their world.
Shimano GRX will help you eliminate excuses, instead encouraging you to try the rough side road or endure in the saddle for much longer.
The purebred GRX FD-RX820 gravel front derailleur is designed for 2x12 speed drivetrains, mounts to a frame braze-on and has a total capacity of 17 teeth. The appropriate chain line for the front derailleur is 47 mm and the chainstay angle is 63-66 °.
The weight of the front derailleur is 270 g.
