Shimano Xtr Di2 Mountain Bike Rear Derailleur Short Cage M9050gs

Shimano XTR Di2 Mountain Bike Rear Derailleur Short Cage M9050GS. The Shimano XTR Di2 RD M9050 GS is part of the most precise and stable drivetrain in mountain biking. The Di2 rear derailleur is a technological marvel of precision and reliability that's built to reward aggressive riding styles. Featuring Shimano Shadow RD stabilization, the derailleur couples unrivaled chain control with shift performance that won't degrade over time. Whether you run a 1x, 2x or 3x drivetrain, the ultra narrow profile helps protect the drivetrain when the trail tightens. Refined rear derailleur geometry further improves performance stability, while Shimano Synchronized Shift compatibility enables system communication with the front derailleur to shift both front and rear derailleurs using a single shifter.
