Shimano GRX Di2 RX815 electric front derailleur for road bikes, double chainring, 11-speed

The Shimano GRX RX815 DI2 front derailleur allows for smooth and fast chainring changes, even under high pedalling torque. It is designed to accommodate a 17-tooth gap between the two chainrings. It also features a chain guide compensation system that adjusts to the chain’s position and can be used in Shimano Synchronized-Shift or semi-synchronised mode.

The Shimano GRX groupset stands out with its Gravel-specific components: Gravel ergonomics, optimised gear-changing options, reliability, and a quiet, stable drivetrain.

Shimano states that this is not a reworked version of its road components, but rather a groupset specifically adapted to the demands of gravel riding.
