The new XT group meets the diverse demands of cross-country bikers, trail bike enthusiasts, and enduro racers with equal conviction, presenting itself as the most versatile high-performance shifting group from Japan.
The Deore XT RD-M8000 rear derailleur features the optimized SHADOW+ technology with a flat angle of attack and an extremely low profile, keeping sensitive components out of harm's way. Shifting performance has been enhanced with newly designed jockey wheels and optimized for cross-running chains.
