The mount is a two-piece cylindrical shell: the battery sits inside the halves, and the whole assembly slides into the steerer tube. Ribs on the exterior compress slightly to fit minor diameter variations in standard 1-1\/8\" round steerer tubes.\u003c\/p\u003e\n\n\u003cp\u003eBefore you commit to this routing, a few things to verify: the Di2 battery measures 152mm long and 16mm in diameter, so your steerer tube needs at least an additional 20mm beyond battery length to accommodate the holder. You'll also need Di2-compatible cables, a Di2-compatible stem and top cap, and handlebars with the small wire ports required for internal Di2 routing. \u003c!-- VERIFY: confirm whether a battery extraction tool is included with the fork steerer version, as noted with the seatpost version --\u003e With the right setup, it's one of the tidier ways to tuck the battery out of sight entirely.\u003c\/p\u003e\n\n\u003ch3\u003ePRO Di2 Internal Battery Holder 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 Di2 internal battery\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSteerer fitment:\u003c\/strong\u003e Standard 1-1\/8\" round steerer tubes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery dimensions:\u003c\/strong\u003e 152mm x 16mm (minimum steerer clearance required)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount design:\u003c\/strong\u003e Two-piece cylindrical shell with compression ribs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e PRAC0085\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"PRO","offers":[{"title":"Default Title","offer_id":43705692880940,"sku":"PRAC0085","price":12.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/pro-di2-internal-battery-holder-for-fork-steerer-7500847.jpg?v=1771299138","url":"https:\/\/ricycles.com\/products\/pro-di2-internal-battery-holder-for-fork-steerer","provider":"RA Cycles","version":"1.0","type":"link"}
