<!--ProdInc[300197430]/Mall:[backcountry_US]-->The last time we saw an update to Shimano''s workhorse XT group was back in 2015 when they made the switch to 11-speed. Fast forward four years and XT gets another refresh, so it comes as no surprise that Shimano''s new XT RD-M8120 Rear Derailleur makes the move to 12-speed, along with other refinements that improve shifting performance while bringing a new level of silence to your drivetrain.
