Ultra-smooth off-road shifting.

The Shimano GRX Di2 FD-RX815-F Front Derailleur is designed for riding on rough road, and provides for ultra-smooth shifting by flawlessly moving your chain up and down your crankset without extra effort. The result is a shift that is precise and direct, with no delay. The GRX Di2 Front Derailleur benefits with lighter front shifting, wider tire clearance, wider range front gearing, and precise electronic shifting.

Features:

  • Operates with Shimano Di2 for digital electronic shifting
  • Chainline is increased by 2.5mm over conventional front derailleurs for greater tire clearance in the front
  • 17t front range provides more gear range in the front
  • Wider tire clearance
  • Wider range front gearing

    I purchase the GRX specifically because it allows more gear options than the Ultegra derailleur. you can use the 10 and 11 gears on my 11-42 cassette and still be on the large front chainring. This cannot be done with the road version.

    The perfect match for GRX cranks

    I recently swapped out the Dura Ace front derailleur on my Diverge for the GRX. It works as well if not better than the DA front derailleur. No missed shifts, no rubbing.
