Description

The Shimano Dura-Ace RD-R9250 12-Speed Rear Derailleur is a work of digitally integrated intelligence. With Di2 technology, this rear derailleur provides quick, smooth, and seamless shifting for unrivaled drivetrain efficiency. It acts as the system's brain, with wireless connectivity to the shifters replacing mechanical wires. The derailleur's button and LED light provide Di2 operating information, while its preset automatic action offers smooth gear changes.

Synchronized Shift chooses the best gear ratio regardless of whether the front or rear derailleurs are engaged. The low-profile Shadow shape improves aerodynamics and has a saver function for crash prevention. It has an 11-34T vast gear ratio capacity for small configurations or typical road doubles. The carbon fiber pulley plates increase rigidity while reducing weight, and the titanium B axle bolt further decreases weight.

The carbon fiber pulley plates increase rigidity while decreasing weight, and the titanium B axle bolt decreases weight even further. This derailleur gives excellent performance thanks to high-tolerance aluminum link plates, four self-lubricating pivot bushings, and durable pulleys. Upgrade to the Dura-Ace RD-R9250 rear derailleur with 12-speed E-tube Di2 compatibility for precise, dependable, and effortless shifting on the road.

Specifications:

  • Digitally integrated intelligence with Di2 technology for fast, smooth, and seamless shifting
  • Wireless connectivity replaces mechanical cables for better performance
  • Buttons and LED lights provide Di2 activity information
  • Preset automatic actions for easy gear changes
  • The synchronized shift that selects the best gear ratio for both front and rear derailleurs
  • A flat shadow shape improves aerodynamics and has a saving function
  • Wide range of gear ratios from 11 to 34 teeth for compact setups or traditional street doubles
  • Carbon fiber pulley plate increases stiffness and reduces weight.
  • Titanium B-axle bolts for even lighter weight
  • High-tolerance aluminum link plates and self-lubricating pivot bushings for low-friction shifting
  • DuPont Zytel pulleys for durability and reduced chain noise
  • Compatible with 12 speed e-tube Di2 system
