Rear Derailleur Shimano Deore XT RD-M8100-SGS 12-speed

Shimano Deore XT RD-M8100-SGS 12v MTB Rear Derailleur

The Shimano Deore XT RD-M8100-SGS 12-speed rear derailleur represents the evolution of Shimano MTB drivetrains, offering even more quick, precise, and quiet shifting performance, even on the most technical terrain.

Completely redesigned, the DEORE XT M8100 derailleur introduces major improvements in chain management and stability, thanks to reduced tension in lower gears and the integration of a new bumper on the pulley cage. The 13-tooth oversized pulleys increase transmission efficiency and improve chain smoothness.

Compatibility with the new Shimano 12v wide-range cassettes (10-51T) significantly expands the gear range, making this derailleur ideal for trail, enduro, and cross-country.
