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.Shifting motor responds instantly to rider inputSeamless gear changes Accurate chain position in every gear Consistent shifting in every gear combinationNew SHIMANO Synchronized Shift System communication with front derailleurAdvantage in all conditions Electric wire transmission guarantees stable performanceChain stabilizer with easy adjustEfficient pulley teeth designCFRP plateTechnologies SEIS, Synchro Shift, E-Tube, Shadow RD+Use: MTBCage: longMount Type: Direct MountTechnology: Shadow RD+Gear rear: 11-speedCompatible Chain: HG-X 11-speedMax. teeth large sprocket: 40T for 3x11 / 42T for 2x11 / 46T for 1x11Min. teeth large sprocket: 40TMin. teeth small sprocket: 11TMax.

The SEIS innovative shift technology is still based on the SHIMANO INDEX SYSTEM (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics. This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobble stone roads and combinations of all of these at the same time. Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting. The shift system allows accurate and effortless shifting in difficult circumstances like when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to mechanical Dual Control Levers so you don’t need to re-program your mind for a new system. Synchro Shift Two derailleurs, One Shifter - Front derailleur reads the rear derailleur’s position and automatically executes front shifts Improves efficiency by minimizing time spent on smaller chainwheels. Programmable synchronized shifting map - The rider chooses when front shifts occur and also chooses rear derailleur command. E-Tube E-Tube platform offers optimum flexibility on your bike. E-TUBE transmits interactive signals and power supply to each parts by “Plug & play” connection. E-TUBE is no rust, no stretch, no freeze and it ensures advanced low maintenance.

Rear Derailleur Stabilizer reduces chain slap. Simple solution for chain drop. Lighter and more efficient than roller type chain device.In order to ensure proper functioning of the electronic Di2 drive system, all components require the same firmware version. The optional diagnostic device allows for reading out or updating the firmware version. An operation of components with different firmware versions may cause a malfunction or loss of function.
