Rear Derailleur Cage + Pulleys Kit for Shimano XT Di2, XTR Di2 11-speed

Now you can use wide-range cassettes (up to 50T) with your 11-speed Shimano MTB Di2 rear derailleurs. 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 11-speed Shimano MTB Di2 rear derailleurs to operate seamlessly with wide-range cassettes, like Garbaruk 11-50T 11-speed model.

 Coupled with Garbaruk oversized derailleur pulleys, our solution provides smoother drivetrain operation and more precise shifting. Also 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  works with XT Di2 RD-M8050 and XTR Di2 RD-M9050 rear derailleurs. Should be coupled with Garbaruk 11+16T derailleur pulleys set with standard bearings.
