Extra range for your 11-speed Road/CX Shimano GRX Di2 rear derailleur

Now you can use wide-range cassettes (up to 50T) with your Road/CX GRX rear derailleur. Just in few simple steps you can enhance the performance and shifting quality of your standard rear mech. Moving the upper derailleur pulley closer to the smallest cassette cog, and lower one further away from the largest cog allows your regular GRX derailleur to operate seamlessly with wide-range cassettes, like  Garbaruk 11-50t speed model.

Coupled with Garbaruk oversized derailleur pulleys, our solution provides smoother drivetrain operation and more precise shifting.
