Rearing to go.

Shimano's RD-R9150 Dura Ace Di2 Rear Derailleur incorporates the Shadow design that made its debut on their mountain bike drivetrains. This low-profile construction better tucks the derailleur body beneath the cassette for more stable shifts, quicker wheel changes, and less exposure to possible damage in a crash. It also keeps a consistent distance between the upper pulley and the cogs across the entire gear range for more precise and reliable shifts on wide 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

Signature will be required when taking delivery of this product.

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 .
