Shimano Dura-Ace R9150 Di2 11sp Rear Derailleur

Shimano Dura-Ace R9150 Di2 11sp Rear Derailleur

Combining the very best of Shimano’s electronic shifting technologies with its race-proven mountain bike “Shadow” cage design, the Dura-Ace R9150 Di2 road bike rear derailleur shifts in an instant and has enhanced aerodynamics. The updated cage position means it rests directly under your frame’s chainstay, reducing drag and protecting it in the event of an unfortunate racing incident.

The Shadow design also offers faster wheel changes thanks to the fact that it moves the derailleur out of the way of the dropouts. It also offers faster and more precise shifting than ever before.

Shimano’s 9150 groupset brings its Syncro-Shift technology to the road too. Syncro-Shift technology enables the front derailleur to read the position of the rear derailleur. The front shift is then automatically operated to position the gears in the most efficient gear and best chain line. This means you’ll never have to worry about front shifting and correction shifts again.
