What Our Gearhead® Experts Are Saying: "I’ve used this derailleur on my trail rig and love how stable the chain stays, even on chunky descents. Shifting is crisp, the Shadow RD+ tech really minimizes chain slap, and it’s an easy upgrade if you’re running a 2x10 setup. Reliable performance at a solid price." When we’re charging down rocky singletrack or climbing tight switchbacks, we rely on the Shimano Deore RD-M6000-GS Rear Derailleur to deliver flawless shifting and chain security. Shimano’s SHADOW RD PLUS technology keeps the drivetrain quiet and chain retention solid so we can focus on the ride, not the noise. Designed for aggressive trail riders, the RD-M6000-GS pairs perfectly with 2x10 setups and features an Optislick cable for smooth, light shifting. Whether we’re upgrading an older drivetrain or dialing in a new build, we appreciate the Shadow RD+ chain stabilizer that effectively minimizes chain slap and reduces the risk of dropped chains.
