Centralized Wireless Shifting with Elite Race Precision

Description

The Shimano Dura-Ace RD-R9250 rear derailleur goes beyond just shifting—it serves as the central hub of the Di2 12-speed system. It integrates the system's charging port and wireless connectivity unit into a single compact body, offering clean setup and hassle-free connection with the rest of your drivetrain.

Fast, Precise, Race-Ready Shifting: Built for elite-level racing and high-performance road riding, the RD-R9250 delivers lightning-fast shifts with pinpoint accuracy. Its advanced motor and refined link design ensure smooth transitions across the cassette—even under load—so you never miss a beat during attacks or sprints.

Shadow Profile for Sleek Aerodynamics: With a low-profile Shadow design, the RD-R9250 sits closer to the frame, improving aerodynamics while reducing exposure to damage. The sleek shape blends into modern race frames and contributes to a quieter, more streamlined ride feel.

Versatility in a Single Cage Length: The derailleur features a single cage length that’s compatible with a wide range of cassettes, accommodating low sprockets from 28T to 34T. This flexibility makes it perfect for riders who want pro-level performance across everything from flat crits to hilly gran fondos.

Whether you're upgrading your current Di2 setup or building a dream race bike, this RD-R9250 rear derailleur brings precision and simplicity together in one smart unit.
