## Overview

The SHIMANO XTR RD-M9100 Rear Derailleur in Stealth Gray is a premium 12-speed drivetrain component crafted from lightweight aluminum. Designed for smooth, quiet, and precise shifting, it features optimized cage lengths for different cassette ranges (10-51T or 10-45T), larger 13t pulley wheels for improved chain stability, and the Shadow RD+ clutch system to minimize chain slap and maximize retention on rugged terrain. Ideal for serious riders seeking top-tier performance and reliability.

## Description

With the release of the XTR M9100 12-speed drivetrain, Shimano jumps right back to the front of the pack by expanding the available gear range and offering better shifting performance than ever before. The new XTR RD-M9100 Rear Derailleur is specifically optimized for Shimano's new wide range cassettes, and features several updates that ultimately lead to smoother and quieter drivetrain operation. It comes in two different cage lengths depending on what gear ratio you choose, letting you select the best option to suit your riding style and preferences. The M9100 Rear Derailleur sees improved chain stability and reduced friction thanks to larger 13t pulley wheels, making it better able to withstand full-force pedaling while shifting gears as smoothly as ever. Shimano was also able to decrease the rear derailleur tension in the lower gear positions, preventing the high chain tension that causes excess friction and noise, and thus a loss of efficiency. The Shadow RD+ clutch system provides excellent chain retention in rough terrain, and keeps annoying chain slap to a minimum. Lastly, the addition of a protective bumper to the inside of the derailleur cage quiets operation even further by cushioning the sound of any chain rub. There are two options available depending on your desired setup. The longer cage SGS model is required for the 10 - 51 tooth XTR 12-speed cassette, but also works with the 10 - 45t Rhythm-Step 12-speed cassette. The GS model features a shorter cage with 28mm more ground clearance for rocky, rooty, and aggressive terrain. It's designed exclusively for the 12-speed 10 - 45t Rhythm-Step cassette.

Review: A+ XTR quality - I've always had really good luck and liked the feel of the xtr derailers. My old 11 speed XTR was almost maintenance free for 4 years and felt better than my bikes with sram GX parts. This is no different. I also like the B screw adjustment line. I'm using it with a Sram 10-50t so I had to tune the B screw a bit more inboard than the 51T line suggested but a little experimenting got it dialed in. Shifts great just like my old 11 speed XTR did, nice crisp precise shifting. Very happy with it.
Review: Shifts great & keeps the chain quite - I managed to Completely snap my original XT derailleur on some logs awhile back on a ride and needed a replacement fast. Unfortunately all I could find that shipped fast was this XTR derailleur. It works great just like the XT but lighter, more expensive, and shinier.

### ⭐⭐⭐ Excellent but there’s a problem
*by L***N on September 26, 2020*

The shimano 12 speed XTR derailleurs are great but suffer from a very bad flaw. I’ve been running both SRAM eagle and XTR 12 speed drives. Both great. The shimano shifts and runs slightly more smoothly than the the SRAM. The shimano cassette has a more progressive gear range. But... there is a major problem with the XTR: the clutch housing is not waterproof. Water can find its way into the clutch from the clutch lever seal and the clutch cover o-ring. Once water gets inside the clutch, it rusts and need to be replaced. I’d recommend lubing both these seals before Installing an XTR derailleur.
