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

Now you can use wide-range cassettes (up to 50T) with your Road/CX GRX rear derailleur. Just in a 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 11-speed model.

Unmatching performance and unique visual experience

Coupled with Garbaruk oversized derailleur pulleys, our solution provides smoother drivetrain operation and more precise shifting. Also, go for our unique cage+pulleys combo if you're looking for a way to make your bike drivetrain stand out like nobody else's does. Our RD cage for Shimano GRX works with RD-RX812 rear derailleur and may be coupled with Garbaruk 11+16T derailleur pulleys set
