Shimano Dura-Ace Rear Derailleur Shadow RD-R9100 11-speed

The Dura-Ace RD-R9100 rear derailleur by Shimano – mechanical shifting at the highest level
With the Dura-Ace RD-R9100 rear derailleur, Shimano introduces the Shadow RD technology, well known from the MTB sector, to the world of road bikes. Thanks to the particularly flat profile, damage is prevented and quiet, clean and safe operation is guaranteed on uneven surfaces. The new direct mount option accommodates frames with thru-axle dropouts. The super-light Dura-Ace rear derailleur is largely made of carbon. Its short cage (SS type) is compatible with 11-speed cassettes up to 11-30 teeth.

Shadow rear derailleurs from Shimano have a very flat profile, allowing for a more aggressive riding style by minimising the risk of getting stuck on obstacles. In addition, the single preload ensures that the rear derailleur does not hit the chain stay even on very uneven ground. All of this contributes to a quiet, clean-operating gearshift.

OT-RS900
For Dura-Ace RD-R9100, Ultegra RD-R8000, 105 RD-R7000 and other 11-speed road or gravel rear derailleurs, Shimano has developed the special OT-RS900 cable housing. It is less stiff than the conventional OT-SP41 housing and is therefore better suited to the tight curve where the cable is routed from the frame to the rear derailleur. Thanks to OT-RS900, problems with the barrel adjuster can be prevented and the rear wheel can be removed more easily. OT-RS900 is not intended for use on the shift/brake lever side.
