Shimano's RD-R9150 Dura Ace Di2 Rear Derailleur uses a low-profile Shadow design that keeps it more closely tucked beneath the cassette for more stable shifting and reduced likelihood of being damaged in a crash. It also allows the upper pulley to maintain a consistent distance from the cogs across all gears for more precise shifting on wider-range cassettes. Compatibility with Shimano Synchro Shift allows both the front and rear derailleur to be controlled by a single shifter up front.

Compatible with Shimano Di2 electronic groupsets only. Claimed weight is 204 g.


Details:

  • Low-Profile Shadow RD Design
  • Largest Cog Size: 30T
  • Minimum Cog Size: 11T
  • Maximum Chainring Difference: 16T
  • Total Capacity: 33T

Little quieter on the shifting & like the new color .

Matches the color of today's matte black finish bikes . Seems to shift a bit quieter when shifting to different gears compared to the old . The only problem I had is that you have to make sure the derailleur is in a slight angle back when mounting on the hanger or else you won't able to take the rear wheel off the bike .
