Wireless Gravel Shifting Built for Range & Resilience

Description

The Shimano GRX Di2 RD-RX827 rear derailleur is engineered for riders who push deep into rough gravel and mixed terrain. Designed for 1x12-speed setups, it delivers fast, reliable electronic shifting with the strength needed for real-world riding. This is GRX performance without compromise.

Wide-Range 1x12 Compatibility: Paired with a 10–51T cassette, the RD-RX827 offers massive range for steep climbs and fast gravel sections. It supports both long adventures and race-paced efforts with equal confidence. Riders get flexibility without sacrificing shift speed.

Automatic Impact Recovery: Built-in automatic impact recovery protects the derailleur from hard trail strikes. The impact-deflecting shape helps it absorb hits and reset instantly. Even after rough encounters, shifting remains precise and consistent.

Shadow ES Stability and Durability: Shimano Shadow ES design refines chain stability with a slimmer and stronger profile. Solid pulley construction improves durability in dusty, rocky conditions. The result is quiet, controlled drivetrain performance on unpredictable surfaces.

Fully wireless Di2 shifting removes external wiring and reduces clutter. It’s designed specifically to handle the vibrations and abuse of gravel riding.

Features

Fully Wireless Shifting: Designed to deliver fast, reliable electronic shifting in rough gravel and mixed-terrain conditions.
Robust Design: Wide link structure, skid-plate design, durable aluminum plate and solid pulley improve strength and longevity.

Technologies
