Description

The Shadow design 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 their Syncro-Shift technology to the road too. Syncro-Shift technology enables the front derailleur to read the position of the rear derailleur and will automatically operate the front shift to position the gears in the most efficient gear and best chain line so you'll never have to worry about front shifting and correction shifts again.

The shadow design places the rear derailleur under the chainstay and cassette to give a slimmer profile, which not only improves aerodynamics but helps prevent damage in a crash.

Customer Reviews

Shimano Dura Ace Di2 R9150 Shadow Rear Derailleur is rated 4.5 out of 5 by 2.
Rated 4 out of 5 by sligi from ok, more difficult to adjust like the old 9070. more noisy.
Date published: 2019-08-12
Rated 5 out of 5 by Whele from Shadow technology gives reliable and almost silent I installed this to replace an older Di2 rear mech that was damaged during a small crash in the winter. The shifting is much better using the shadow technology and is so smooth and silent I sometimes have to check that it has actually changed gear at all!!!.
