The Shimano XTR Di2 M9050 Shadow rear derailleur delivers unprecedented precision that stays intact over time.
This derailleur is equipped with Shadow technology offering very high performance. Its Shadow profile is even more compact than the previous M980 series, so you'll be able to engage even harder in tight, winding sections without the risk of catching the rear derailleur.
Only compatible with other components of the XTR Di2 power pack
