Unrivaled Shift and Performance Stability:
Shimano’s XTR M9050 Di2 rear derailleur delivers unrivaled chain control and shift performance that doesn’t degrade over time. With Shimano Shadow RD+ clutch technology, the RD-M9050 is the ultimate mountain bike rear derailleur. Its profile is narrower than ever, helping you squeeze through tight sections without worry of damage.
A refined geometry augments Shimano’s already legendary performance stability while system communication with the front derailleur makes Shimano Synchronized Shift a possibility.
