It is based on the \u003cstrong\u003eDUAL CONTROL LEVER\u003c\/strong\u003e concept, which combines electronic shifting and hydraulic braking in a single control. On this left-hand model, the lever controls the chainring shifting function (2x), while the brake section operates the bike's hydraulic system, all controlled by \u003cstrong\u003eShimano Di2\u003c\/strong\u003e technology and compatible with \u003cstrong\u003eSynchro-Shift\u003c\/strong\u003e mode, which automatically synchronises the front and rear derailleurs.\u003c\/p\u003e\n\u003cp\u003eThe lever ergonomics have been specifically developed for gravel riding: the raised hood head limits hand misalignment and slipping, while a notch dedicated to finger positioning prevents any upward slipping on rough sections. The brake lever benefits from an \u003cstrong\u003eanti-slip coating\u003c\/strong\u003e and a ribbed texture that improve grip even in wet or muddy conditions, as well as a raised pivot axis and curved shape that increase braking efficiency while reducing fatigue over long distances.\u003c\/p\u003e\n\u003cp\u003eOn the braking side, the lever incorporates \u003cstrong\u003eSERVO WAVE\u003c\/strong\u003e technology, which quickly brings the pads closer to the disc before providing precise modulation through the rest of the lever stroke, for mineral-oil hydraulic operation compatible with \u003cstrong\u003eFlat Mount\u003c\/strong\u003e callipers. The body is made from glass-fibre-reinforced plastic (GFRP), and a \u003cstrong\u003ereach adjustment\u003c\/strong\u003e system allows the distance between the lever and handlebar to be adapted to any hand size. Two E-Tube ports allow connection to the rest of the Di2 groupset via the \u003cstrong\u003eE-TUBE PROJECT\u003c\/strong\u003e app, for complete customisation of button functions.\u003c\/p\u003e","brand":"SHIMANO","offers":[{"title":"Default Title","offer_id":57417985589628,"sku":"PBS_SHIM079016","price":209.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/3444\/9318\/files\/ST-RX815-L_C219_1_750_750.jpg?v=1788945593","url":"https:\/\/probikeshop-irl.com\/products\/left-lever-shimano-grx-di2-st-rx815","provider":"Probikeshop","version":"1.0","type":"link"}
