  • Shimano XT RD-M8100 12-Speed Rear Derailleur Shadow+ GS Medium Cage
  • Shimano XT RD-M8100 12-Speed Rear Derailleur Shadow+ GS Medium Cage

Description

The XT Shadow Plus 12-speed rear derailleur offers fast and precise shifting performance, optimized to conquer any trail.

The all-new Shimano Deore XT M8100 series derailleurs elevate drivetrain silence through decreased tension in the low gear position and an added bumper on the pulley cage. Larger 13-tooth pulleys enhance efficiency and chain management, while compatibility with Shimano's new 12-speed cassettes expands the gear range.

Technology: 

Hyperglide+ drivetrain’s redesigned cassette and chain enhance the next generation of MTB riding by improving speed, shifting efficiency, and smoothness over any terrain.

Key Features:

- Improved Chain Engagement: Stronger retention and smoother pedalling provide greater power and confidence over rapidly changing terrain.
- Enhanced Shifting: Definitive up and down shifting in both directions boosts riders’ concentration and acceleration.
- Ultra-Efficient Drivetrain: Smoother power transmission increases comfort and reduces rider stress.
- Wide Gear Range: Offers various cassette options and the choice of a single or double front chainring, supporting diverse MTB riding styles and preferences.
- Continuous Pedaling: Enables riding over virtually any terrain with the revamped drive system and dedicated chain, delivering fast shifting, efficient power transfer, and unmatched chain stability.
- Smooth Operation: Helps riders adapt to drastically changing trail conditions by precisely judging the optimal shifting moment.
- Reduced Pedaling Shock: Cuts shifting times by a third compared to the current HG system, allowing seamless maneuvering over rough trails.

Shimano Shadow RD+
- Less Distraction: Quieter drivetrain with a rear derailleur stabilizer that reduces chain slap.
- Chain Drop Prevention: Simple solution that is lighter and more efficient than roller-type chain devices.
- Advanced Design: Super low profile and optimized slant angle for super light shifting action.
- Chain Stabilizing Switch: Reduces chain bounce in rough terrain, maintaining a more stable drive and shifting.
- Silent Ride: Single tension spring prevents contact with the chainstay, and a rubber bumper on the pulley cage adds to the silent drive.
- Efficient Performance: Features 13-tooth pulleys and decreased derailleur tension to prevent high chain tension in low gears.
- Durable Build: Cold-forged wide alloy links, pivot body, and four fluorine-coated link pin bushings for durability.
- Positive Shifting Feel: Strong return spring enhances the shifting experience.
- Optimized for XT M8100 12-Speed Drivetrains: Durable sealed 13-tooth bearing pulleys reduce friction and are specifically designed for 1x drivetrains.
- Direct Cable Routing: Prevents snagging from trail hazards.
- Specifications: Max low sprocket: 45/51 tooth (1x12-speed), average weight: 284g.

    XT is a joy

    Replaced the SRAM axs xplr set up for the XT and couldn't be happier.

    Shifts are super smooth, absolutely love this groupset

    Better performance imho than the axs xplr and with the added reassurance of not having to deal with batteries.

    Great performance and value

    I've always chosen XT, very reliable, great performance and currently a very good price, I've been after the GS cage version for ages, finally supplies are coming back to normal.
