Paired with hydraulic disc braking, the lever gives you consistent, modulated stopping power whether you're descending in the dry or riding into a wet headwind. Sold individually as a left or right unit, it integrates cleanly into a full 105 Di2 build.\u003c\/p\u003e\n\n\u003cp\u003eThe ergonomic lever body is designed to accommodate a natural hand position on both the hoods and in the drops, and the reach can be adjusted to suit different hand sizes. Shifting is handled by button actuation rather than a mechanical pivot — small inputs translate directly to precise electronic signals, with no cable stretch or adjustment drift over time. The result is a cockpit that stays tidy and a system that maintains its responsiveness across long miles.\u003c\/p\u003e\n\n\u003ch3\u003eShimano 105 Di2 7170 Disc Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Shimano 105 Di2 7170 series groupset\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrake type:\u003c\/strong\u003e Hydraulic disc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShifting system:\u003c\/strong\u003e Electronic (Di2)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable options:\u003c\/strong\u003e Left (front brake \/ front derailleur) or Right (rear brake \/ rear derailleur)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Black \/ Left","offer_id":43519848546348,"sku":"ISTR7170LE","price":325.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ Right","offer_id":43519848579116,"sku":"ISTR7170RE","price":325.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-105-di2-7170-disc-brake-shifter-4286462.jpg?v=1771298118","url":"https:\/\/ricycles.com\/products\/shimano-105-di2-7170-disc-brake-shifter","provider":"RA Cycles","version":"1.0","type":"link"}
