{"product_id":"shimano-xt-rdm8100-rear-derailleur-1741986","title":"Shimano XT RDM8100 Rear Derailleur","description":"\u003cp\u003eThe rattle of a chain against the frame is a distraction you don’t need when you’re hunting for the perfect line through a root-strewn descent. Shimano engineered the XT RD-M8100 to silence that chaos, utilizing a dampened pulley cage and refined tension profiles that keep your drivetrain eerily quiet even when the trail turns rowdy. By bumping the pulley wheels up to 13T, the system flows with less friction, translating your pedal strokes into immediate, authoritative momentum. Whether you are grinding through a steep, sustained climb in the middle of a massive backcountry loop or sprinting over jagged, technical terrain, this 12-speed workhorse offers the range to conquer 51T cassettes without breaking a sweat. It feels less like a mechanical component and more like a permanent extension of your intent, delivering crisp, reliable shifts that allow you to focus entirely on the horizon ahead.  \u003cbr\u003e  \u003cbr\u003e\u003cstrong\u003ePRODUCT CONDITION\u003c\/strong\u003e \u003cbr\u003e  \u003cbr\u003e\u003cspan class=\"UnNewText\"\u003eThis UnNew \u003c\/span\u003e\u003cspan id=\"displayNameDesc\"\u003eShimano XT RDM8100 Rear Derailleur \u003c\/span\u003e is in \u003cspan class=\"condition\"\u003eExcellent\u003c\/span\u003e condition.  \u003cbr\u003e  \u003cbr\u003e\u003cspan class=\"conditionText\"\u003eProducts in Excellent condition have seen minimal use and wear.
