Shimano RD-M8200 Deore XT mechanical, 12-speed, Shadow ES, SGS

XT Shadow ES 12-speed mechanical rear derailleur for fast and precise shifting performance and durability

The Shadow ES system is also zero maintenance and has no degradation of performance
Unique structure using two springs has a tighter chain wrap that improves shifting and security with increased spring force by 70%, allowing the chain to mesh firmly with the sprocket
With the tighter chain wrap skipping is prevented even as the cogs wear
Solid pulleys to minimize debris entry and ensure durability
Direct cable routing prevents snagging from any trail side hazards
Cold forged wide alloy links and pivot body
Four fluorine-coated link pin bushings
Strong return spring for a positive shifting feel
Top normal spring uses the spring to select higher gears
