Cold-forged aluminum arms built with Hollowtech II construction keep weight down while delivering the kind of bottom-bracket stiffness that translates directly into power on climbs and technical terrain.\u003c\/p\u003e\n\n\u003cp\u003eThis is the 2x12-speed version, designed around a 52mm chainline and Boost spacing — the wider hub standard that stiffens the wheel build and sharpens the overall drivetrain geometry. A 172mm Q-Factor keeps your feet in a narrow, efficient stance throughout the pedal stroke, and the direct-mount chainring interface means the 36x26 ring combination seats securely with minimal flex under load. Three crank arm lengths — 165, 170, and 175mm — let you dial in fit based on your riding style and anatomy.\u003c\/p\u003e\n\n\u003ch3\u003eShimano XT FC-M8100-2 Boost Crankset Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Cold-forged aluminum (Hollowtech II)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeeds:\u003c\/strong\u003e 12-speed, 2x\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChainring Options:\u003c\/strong\u003e 36x26T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChainline:\u003c\/strong\u003e 52mm (Boost)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQ-Factor:\u003c\/strong\u003e 172mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrank Arm Lengths:\u003c\/strong\u003e 165, 170, 175mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 650g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"36x26 \/ Black \/ 165mm","offer_id":43520607354924,"sku":"IFCM81202BAX66","price":280.0,"currency_code":"USD","in_stock":true},{"title":"36x26 \/ Black \/ 170mm","offer_id":43520607387692,"sku":"IFCM81202BCX66","price":280.0,"currency_code":"USD","in_stock":true},{"title":"36x26 \/ Black \/ 175mm","offer_id":43520607420460,"sku":"IFCM81202BEX66","price":280.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-xt-fc-m8100-2-boost-crankset-7288007.jpg?v=1771297269","url":"https:\/\/ricycles.com\/products\/shimano-xt-fc-m8100-2-boost-crankset","provider":"RA Cycles","version":"1.0","type":"link"}
