The upper (guide) pulley sets shift-feel; the lower (tension) pulley keeps chain tension. Both are wear-parts on a high-mileage drivetrain and a service-kit replacement. Dura-Ace is Shimano's top-tier road groupset — the same parts the WorldTour peloton runs. Weight-optimised, finished to the tightest tolerances in the range. This is the Shimano Dura-Ace R9250 Rear Derailleur Pulley Set.\u003c\/p\u003e\u003ch3\u003eDetails\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest for:\u003c\/strong\u003e\u003cbr\u003ehigh-mileage pulley wear replacement\u003cbr\u003erebuilding an older-series RD for continued use\u003cbr\u003ekeeping a spare set on the shelf for team \/ race support\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e\u003cbr\u003e11T upper + lower-profile lower pulley\u003cbr\u003eSealed bearings at the guide pulley\u003cbr\u003eMatched to the named RD series\u003c\/p\u003e\u003ch3\u003eInstallation \u0026amp; Care\u003c\/h3\u003e\u003cp\u003eInstall with the correct Allen key; torque to Shimano spec.
