Shimano's RD-R9100 Dura Ace 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.

Compatible with Shimano 11-speed road groups.


Details:

  • Low-Profile Shadow RD Design
  • Largest Cog Size: 30T
  • Minimum Cog Size: 11T
  • Maximum Chainring Difference: 16T
  • Total Capacity: 35T

Superb function. Gorgeous to look at.

I'm an older, semi-fast recreational road rider with over 30 years experience with top of the line group sets. These include Campy, Shimano and even Suntour. I had a full Dura Ace 7900 group on my Litespeed Archon T1 and the shifting was dialed. In fact everything worked so damn well. But then I decided to do an upgrade to a Dura Ace 9100 mechanical group, mostly because I just dig the hell out of the way it looks. After I installed, adjusted and rode the new set up, I was just amazed that the front and rear shifting was far better than the 7900 group. Another thing that I'll have to wait to verify, but the drivetrain is silent. I haven't had much riding time on it, maybe 150 miles and haven't lubed the Dura Ace chain yet. It still has the packing grease. I'll see what it sounds like when I lube it.

The reason I only gave 4 stars for value is that I'm pretty sure Ultegra would function just as well, but at 12 the price. The glossy finish on the Dura Ace makes me swoon.

Excellent derailleur, excellent service

Replaced broken derailleur, my fault. New unit is exception. Clean sharp shifts and very smooth operation in every way. Simply the best. Shimano is proud of their product and price is always on the high side. Great deal with BTD and ordering and shipping is esy and swift. Plus points adds to the value.
