The Shimano Deore XT M8000 rear derailleur receives a complete makeover and as a result it features Shimano's pioneering Shadow RD technology and a refined geometry for increased stability. The Shadow Plus rear derailleur follow the range topping XTR in providing a lighter shift effort, with external adjustability and increased clutch tension range, and an even lower profile for improved clearance from trail hazards. The derailleur provides a light action through the shifter which results in a positive and perfectly executed shift as well as a smooth journey throughout the cassette. Key Features: - Shadow Plus chain stabilization technology reduces chain slap for a quieter ride and increased stability. - Direct Mount compatible system for easier wheel removal and frame design flexibility. - Low profile design minimizes risk of damage from trailside obstacles. - Externally adjustable chain tension stabilizer. - Four fluorine-coated link pin bushings ensure smooth and slick shifting.
