The product is in full functioning order.\u003c\/p\u003e\n\n\u003cp\u003eThe Shimano GRX FC-RX820-1 crankset pairs a 172.5mm arm length with a single 40T chainring on a 110mm Shimano Asymmetric BCD, built for 12-speed gravel drivetrains. Hollowtech II hollow-forged construction keeps the arms stiff while trimming mass, and the splined Hollowtech II spindle interface delivers a secure, consistent connection between crank and bottom bracket.\u003c\/p\u003e\u003cp\u003eThis crankset suits mixed-terrain gravel riding, balancing durability and mud clearance while keeping chain retention solid. A 49.7mm chainline and 151mm Q-factor work with 10-45T or 10-51T cassettes, and the crank is compatible with 135\/142mm Road Disc hubs on chainstays under or over 415mm. Pedal threads are standard 9\/16 inch; a bottom bracket is sold separately.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQuick Facts\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%; border-collapse: collapse; border: 1px solid #ddd;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color: #F2F2F2; text-align: left;\"\u003e\n\u003cth style=\"padding: 12px; border: 1px solid #ddd;\"\u003eFeature\u003c\/th\u003e\n\u003cth style=\"padding: 12px; border: 1px solid #ddd;\"\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003eCrank arm length\u003c\/td\u003e\n\u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e172.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003eChainring\u003c\/td\u003e\n\u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e40T, 110mm Shimano Asymmetric BCD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003eDrivetrain speed\u003c\/td\u003e\n\u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e12-speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003eChainline \/ Q-factor\u003c\/td\u003e\n\u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e49.7mm chainline, 151mm Q-factor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003eClaimed weight\u003c\/td\u003e\n\u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e644 grams\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Shimano","offers":[{"title":"Default Title","offer_id":43497012920383,"sku":"210000133940","price":340.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0066\/2283\/8853\/files\/open-box-shimano-grx-fc-rx820-1-crankset-172-5mm-40t-parts-cranksets-1261201125.png?v=1791248867","url":"https:\/\/bici.cc\/products\/open-box-shimano-grx-fc-rx820-1-crankset-172-5mm-40t","provider":"Bici","version":"1.0","type":"link"}
