Compared to its predecessor, the RX820 caliper is designed to deliver a more immediate initial bite point alongside improved feel throughout the braking range, giving you more precise control when the road turns loose or the gradient steepens.\u003c\/p\u003e\n\n\u003cp\u003eShimano engineered the RX820 with \u003cstrong\u003e10% wider pad clearance\u003c\/strong\u003e than the previous generation, which reduces rotor contact and drag while also quieting the caliper on rough surfaces. The housing is more compact, making wheel removal and trail-side maintenance more straightforward. A one-way bleeding process simplifies hydraulic servicing — less time bleeding, more time riding.\u003c\/p\u003e\n\n\u003ch3\u003eShimano GRX RX820 Disc Brake Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eGroupset: Shimano GRX RX820 (12-speed)\u003c\/li\u003e\n  \u003cli\u003eType: Hydraulic disc brake caliper — rear\u003c\/li\u003e\n  \u003cli\u003ePad clearance: 10% wider than previous generation for reduced noise and drag\u003c\/li\u003e\n  \u003cli\u003eBleeding: One-way hydraulic bleeding system\u003c\/li\u003e\n  \u003cli\u003eColour: Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Black","offer_id":43520174391340,"sku":"IBRRX820RDRF","price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-grx-rx820-disc-brake-caliper-rear-1339141.jpg?v=1771297812","url":"https:\/\/ricycles.com\/products\/shimano-grx-rx820-disc-brake-caliper-rear","provider":"RA Cycles","version":"1.0","type":"link"}
