SHIMANO DEORE XT RD-M8120 SGS REAR DERAILLEUR (12-SPEED | LONG CAGE | 290 G)
The Shimano Deore XT RD-M8120-SGS rear derailleur sets the standard for precise and reliable shifting in demanding MTB use. It was developed specifically for modern 12-speed drivetrains (especially 2x12-speed setups) and impresses with extremely fast, smooth gear changes on the trail.
Thanks to proven Shimano Shadow RD+ technology with an integrated friction damper, chain slap is effectively minimized – for a whisper-quiet drivetrain and secure chain retention even on rough terrain. Standard mounting and the long cage (SGS) ensure optimal capacity and perfect shifting performance under load.
