A dedicated Li-ion battery sits contained behind a removable cover to protect from the elements and the main cage has been massively toughened. \u003c\/p\u003e\n\u003cp\u003eThe shifter is also all new, with separate buttons that mimic the feel of a mechanical system while providing the speed and accuracy of wireless. Fully customisable, both switches can be adjusted to user preference, while a third button controls everything from micro adjust to auto shift modes.\u003c\/p\u003e\n\u003cp\u003ePack contains:\u003c\/p\u003e\n\u003cp\u003eDerailleur, Shifter, Derailleur Battery, Charger, Shifter Coin Cells, 12 Spd Quick Link. \u003c\/p\u003e","brand":"Shimano","offers":[{"title":"Default Title","offer_id":55448857018743,"sku":"SHIM-GPM8250ISGS","price":549.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0281\/2769\/0849\/files\/Shimano-XTDi2UpgradeKit-ISpec-SGS-2025-TweedValleyBikes.jpg?v=1752588230","url":"https:\/\/tweedvalleybikes.mom\/products\/shimano-xt-di2-upgrade-kit","provider":"Tweed Valley Bikes","version":"1.0","type":"link"}
