🚴 Why Choose the Garbaruk Rear Derailleur Cage for Shimano GRX 11-speed?

Shimano’s stock GRX rear derailleur does many things well, but running a massive cassette straight out of the box ain’t one of them. That’s where the Garbaruk Rear Derailleur Cage for Shimano GRX 11-speed comes in.

Engineered specifically for the RD-RX812 mechanical derailleur, Garbaruk’s cage transforms your drivetrain by allowing you to run wide-range cassettes up to 50 teeth. Whether you’re climbing steep backcountry tracks, hauling gear across continents, or just want more low end gearing, Garbaruk has you covered.

Machined in Poland from high-strength 7075-T651 aluminium, this cage is as tough as it is light, and the finish is as crisp as the shifting. By reconfiguring the pulley positions, it optimises the derailleur’s movement to handle larger cogs smoothly and reliably. The result? Better shifting across the entire range and less drivetrain stress on those long, grindy climbs.

Want to punch it up a notch? Pair it with a set of Garbaruk’s oversized pulleys for even better performance.
