Q
Is the left hand shifter compatible with 2x drivetrain?
Asked by Tris (West Midlands) — 17 Jul 2026
1. Hi there, Yes. The left-hand GRX 600 STI lever (ST-RX600-L) is the front shifter for a 2x setup, controlling a double front derailleur across 11-speed. Just make sure you're selecting the left lever option here rather than the right. Many thanks

About Shimano

Shifting the way the world rides.

From a single Osaka workshop in 1921, Shimano has grown into the world's most influential component maker. The brand's relentless engineering — Dura-Ace, Ultegra, GRX, XTR — has shaped the way the world shifts, brakes and rides, on the road and off it.

Shimano's flagship groupset, Dura-Ace, has been the benchmark for top-level road components for more than five decades. Every refinement that lands on Dura-Ace eventually shapes the entire Shimano range, all the way down to entry-level drivetrains.
