Shimano Deore XT GS RD-M8100 12v Rear Derailleur

The Shimano Deore XT GS RD-M8100 12v rear derailleur represents the benchmark for next-generation MTB drivetrains.
Completely renewed, the SHIMANO DEORE XT M8100 series introduces a new level of quietness and precision, enhancing the riding experience on any terrain.

Thanks to the chain tension reduction when the lowest gear is selected and the addition of a bumper on the pulley cage, the derailleur ensures smooth and quiet pedaling even on the most demanding trails.
The 13-tooth oversized pulleys (13T) improve chain management and increase overall system efficiency.
Perfectly compatible with Shimano 12v cassettes (10-45T), it offers stable, precise, and fast shifting, ideal for those seeking high-level performance in any condition.

Main features

  • Greater ground clearance:
    Designed for an aggressive riding style, it offers higher ground clearance, ideal for tackling technical trails and obstacles.

  • 28 mm higher ground clearance compared to the RD-M8100-SGS model:
    Ensures better obstacle clearance and reduces the risk of impacts.

  • Ultralight short cage design:
    Facilitates smooth rear suspension movement, improving bike handling on descents and rough terrain.

  • Fast and precise shifting performance:
    Optimized to offer immediate and stable gear shifts, regardless of the type of terrain.

  • Silent transmission:
    Reduced tension on the lowest gear and the new pad on the pulley cage minimize vibrations and noise during pedaling.

  • Enlarged 13T pulleys:
    They improve chain smoothness and increase overall drivetrain efficiency.

  • Stability on rough terrain:
    The robust construction ensures stable and precise shifting even in the toughest conditions.

    Designed for 1x12 speed drivetrains with Shimano 10-45T cassette.
