{"product_id":"shimano-grx-rx820-1x-crankset","title":"Shimano GRX RX820 1x Crankset","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eShimano GRX RX820 1x Crankset\u003c\/strong\u003e is built for gravel riders who want a clean, single-ring drivetrain without compromising on power transfer or durability. Hollowtech II arm construction keeps the crank arms stiff where it matters — out of the saddle on a loose climb, or pushing through the pedals on a long mixed-terrain effort — while holding weight down relative to a solid-arm design.\u003c\/p\u003e\n\n\u003cp\u003eTwo chainring sizes, 40t and 42t, pair with either a 10-45T or 10-51T cassette, giving you the flexibility to tailor your gear range to the terrain you ride most. Three crank lengths — 170mm, 172.5mm, and 175mm — mean you can dial in a fit that works with your pedalling mechanics rather than adapting to whatever's on the shelf. At RX820 spec, this sits at the upper tier of the GRX family, bringing a level of finish and refinement you feel in every pedal stroke.\u003c\/p\u003e\n\n\u003ch3\u003eShimano GRX RX820 1x Crankset Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChainring options:\u003c\/strong\u003e 40t, 42t\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrank arm lengths:\u003c\/strong\u003e 170mm, 172.5mm, 175mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Hollowtech II arms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible cassettes:\u003c\/strong\u003e 10-45T, 10-51T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"40t \/ Black \/ 170mm","offer_id":43520174686252,"sku":"IFCRX8201CXB0","price":280.0,"currency_code":"USD","in_stock":true},{"title":"42t \/ Black \/ 170mm","offer_id":43520174719020,"sku":"IFCRX8201CXB2","price":280.0,"currency_code":"USD","in_stock":true},{"title":"40t \/ Black \/ 172.5mm","offer_id":43520174751788,"sku":"IFCRX8201DXB0","price":280.0,"currency_code":"USD","in_stock":true},{"title":"42t \/ Black \/ 172.5mm","offer_id":43520174784556,"sku":"IFCRX8201DXB2","price":280.0,"currency_code":"USD","in_stock":true},{"title":"40t \/ Black \/ 175mm","offer_id":43520174817324,"sku":"IFCRX8201EXB0","price":280.0,"currency_code":"USD","in_stock":true},{"title":"42t \/ Black \/ 175mm","offer_id":43520174850092,"sku":"IFCRX8201EXB2","price":280.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-grx-rx820-1x-crankset-7603367.jpg?v=1771297812","url":"https:\/\/ricycles.com\/products\/shimano-grx-rx820-1x-crankset","provider":"RA Cycles","version":"1.0","type":"link"}
