Shimano Deore XT RD-M8200-SGS Rear DerailleurShimano's toughest mechanical 12-speed derailleur yet — built for riders who don't let up, whether that's an enduro stage or a full day out on the trail.
The biggest change from previous XT generations is the new low-profile, wedge-shaped body. Instead of taking trail impacts head-on, it's shaped to glance off rocks and roots. An internal spring absorbs the hit and snaps the derailleur straight back into position, so a stray pedal strike stays a non-event instead of turning into a trailside fix.
SHADOW ES clutch technologyA wider, beefed-up version of Shimano's original SHADOW clutch. It holds your chain firmly in place and keeps things quiet over rough ground. Covered pulleys and shielded pulley teeth add extra protection against dirt and debris getting into the drivetrain and affecting your shifting.
Huge range, precise shifting
HYPERGLIDE+ tech and a massive 510% gear range mean this derailleur pairs with any 10-51T 12-speed cassette, giving you fast, confident shifts under load no matter the gradient.
