Shimano XTR Di2 FDM 9050 front derailleur

The new Shimano XTR 11-speed Di2 electronic components, designed for use ranging from cross-country to enduro. Available with a crankset featuring 1–3 chainrings and an 11-speed cassette with an 11–40 tooth range.

Shimano XTR Di2:

Shimano’s XTR M9050 Di2 shifting system enables the seamless control and immediate response that only digital shifting with the M9000 Rhythm Step drivetrain can offer. This heralds the digital age for mountain bikers, bringing with it a previously unknown level of control whilst riding, regardless of the discipline. The combination of Di2 with close gear ratios means that shifting becomes second nature. Less effort is required when shifting, and superb ergonomics ensure effortless gear changes, allowing your hand to remain firmly on the handlebars, so you always have perfect control over riding manoeuvres and gear changes. With the XTR Di2 system, gear changes are virtually effortless, even on the MTB groupset, achieved by briefly or firmly pressing the Firebolt shift levers.

Shimano XTR Di2 programming:

Individual assignment of shifting functions and shift levers is possible. Control of the front derailleur can be assigned from the left to the right shift lever, and that of the rear derailleur from the right to the left. The programmable Multi-Shift function allows a maximum of eleven gears to be shifted at once whilst the shift lever is held down. Furthermore, the entire drivetrain, including the front derailleur and rear derailleur, can be operated using a single Firebolt shifter. Shimano calls this feature Synchro Shift. Depending on the position of the rear derailleur, the front derailleur knows when it needs to shift and carries out the corresponding shifting operations on the crankset. The shifting speed is also programmable.

Shimano Di2 XTR FD-M9050 front derailleur

Only the finest materials are used in the XTR 11-speed front derailleur FD-M9050; perfectly matched to the new 11-speed XTR Di2 components, the XTR front derailleurs offer outstanding shifting performance. The front derailleur function can be programmed in three modes and can then shift to the next gear fully automatically.

Shimano XTR 9050 front derailleur compatibility:

The new Shimano 11-speed XTR Di2 series is only compatible with the XTR 11-speed SLWM9050 shift levers. The HG-900 chain is recommended. The 11-speed XTR cassettes are also compatible with 9-10-speed Shimano-compatible freehub bodies. These derailleurs also require derailleur hangers or mounting plates for High Direct or E-Type S3 mounting.

Shimano Di2 installation:

Installing Shimano Di2 components is almost easier than fitting traditional derailleurs. The standardised E-Tube cable connectors and the Junction B distribution box ensure straightforward and quick installation. The shift lever(s) are connected to the display; a cable runs from the display to the Junction B hub, and from there the cables run to the rear derailleur, front derailleur and battery. The battery can be mounted externally on the bottle cage, or internally in the seat tube, down tube or steerer tube. Frames specifically designed for this purpose are required for internal cable routing.

Shimano Di2 Junction B Port:

The Junction B junction box is responsible for connecting the rear derailleur, front derailleur, battery and shift levers. The Junction B port is available in two versions: the internal SMJC41, for fully internal routing, and the SMJC40 for mounting beneath the bottom bracket, should fully internal routing not be possible.

The SMBTC1 battery holder is available as an option. This allows for external mounting of the SMBTR2 round battery. At the same time, the SMBTC1 battery holder provides the Junction B connections – a total of 6 ports – meaning the additional Junction B port is not required. The additional 2 ports not used by the drivetrain can be used to power electric suspension components.
