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.
