Precise smooth shifting: with the XT 11-speed Rear Derailleur RD-M8000 GS Shadow+ from Shimano

The rear derailleur DEORE XT M8000 receives a complete makeover. The DEORE XT M8000 rear derailleur features Shimanos optimized SHADOW RD+ technology with a shallow angle and extremely low profile design, reducing shift effort and improving chain stability, resulting in sharp and silky gear changes. Meanwhile new high efficiency pulleys adapted for cross-chain riding feature a taller tooth profile for improved shifting. SHADOW RD+ friction clutch technology from the XTR range has been incorporated with increased ease of adjustment for either maximum stability or lower shift effort. The DEORE XT M8000 rear derailleur is compatible direct mount systems and 1×11 and 2×11 GS or 3×11 SGS set ups.
