Orbit uses Sachs' own system, where the sprocket block works with the hub's specific freewheel design.\nSee the manual below.\n\u003ca href=\"https:\/\/www.velovintage.dk\/wp-content\/uploads\/2026\/09\/orbit-commander-sachs-huret-workshop-guide.pdf\" target=\"_blank\" rel=\"noopener\"\u003eorbit-commander-sachs-huret-workshop-guide\u003c\/a\u003e\n\n\u003ca href=\"https:\/\/www.velovintage.dk\/wp-content\/uploads\/2026\/09\/orbit-sachs-huret-commander-12gang-schaltsystem.pdf\"\u003eorbit-sachs-huret-commander-12gang-schaltsystem\u003c\/a\u003e","brand":"Sachs","offers":[{"title":"Default Title","offer_id":57739454939476,"sku":"60 0100 008 001","price":1991.0,"currency_code":"NOK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/6607\/4452\/files\/Sachs_Orbit-H12100-2x6-6.jpg?v=1792492565","url":"https:\/\/svgbij-8n.myshopify.com\/en\/products\/nos-sachs-orbit-h-12100-nav-60-0100-008-001-2-6-speed-nav-inkl-maillard-13-15-17-20-24-28t-krans","provider":"Velovintage","version":"1.0","type":"link"}
