The lever's ergonomics are shaped for the varied hand positions that gravel riding demands, giving you confident reach whether you're upright on a fire road or tucked in on pavement.\u003c\/p\u003e\n\n\u003cp\u003eThe BR-RX810 caliper is flat-mount and built with anti-mud properties to keep the hydraulic system functioning when conditions turn dirty. Heat dissipation is handled well enough for extended descents, and the bleeding system is straightforward — tool access and wheel removal are designed to stay clean and simple. Hydraulic modulation here gives you more control over braking power than a cable system would, which matters most when surfaces are loose or wet.\u003c\/p\u003e\n\n\u003ch3\u003eShimano GRX BL-RX810\/BR-RX810 Left Side Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Left side only — lever, caliper, and hose included\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLever weight:\u003c\/strong\u003e 164g\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliper weight:\u003c\/strong\u003e 140g\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e 11-speed mechanical shifting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliper mount:\u003c\/strong\u003e Flat mount\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Black","offer_id":43583179063340,"sku":"IRX8104DLF6SC100","price":226.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-grx-bl-rx810br-rx810-left-side-hydraulic-brake-levercaliper-3267589.jpg?v=1771295229","url":"https:\/\/ricycles.com\/products\/shimano-grx-bl-rx810-br-rx810-left-side-hydraulic-brake-lever-caliper","provider":"RA Cycles","version":"1.0","type":"link"}
