Description

Shimano's RD-R9150 Dura-Ace Di2 11-speed 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
  • 11 speed

Shimano Durace Di2 Rear Derailleur

I had to replace my wife's rear derailleur after partially running over her bike with our car after a bike ride. She had an earlier model of the Di2 rear derailleur, but this newer version worked perfectly. It is super easy to install, looks great and shifts beautifully. True plug and play replacement.

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 .

It's Dura Ace. You know it shifts better than anything else, so you might as well get it.
