Crafted with induction-hardened, mirror-lapped bearing raceways and high-tensile chrome-finished steel cups, it offers exceptionally smooth steering response and immense fatigue endurance under race conditions. Sized to the 1\" ISO standard with a 26.4 mm crown race, this headset is a rare, investment-grade component for top-level early Dura-Ace builds.\u003c\/p\u003e","brand":"Goldensteelcycles","offers":[{"title":"Default Title","offer_id":59340713132377,"sku":null,"price":79.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0805\/6609\/2121\/files\/headset-dura-ace-1st-gen_1.jpg?v=1788887926","url":"https:\/\/goldensteelcycles.com\/products\/shimano-dura-ace-first-generation-crane-ga-200-vintage-headset-1-iso-threaded","provider":"Goldensteelcycles","version":"1.0","type":"link"}
