This premium vintage Koga-Miyata Pro frameset represents the absolute golden era of professional steel racing, meticulously constructed from Miyata's proprietary, top-tier Hardlite Spline FM-1 chrome-molybdenum steel. This legendary tubing features an advanced triple-butting process enhanced with unique internal spiral reinforcements (splines) down the main tubes. This brilliant engineering creates an incredibly stiff bottom bracket junction for explosive power transfer while maintaining a compliant, lively ride quality to damp harsh road vibrations.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003eWhat truly elevates the Pro series is its rich racing pedigree and stunning attention to technical detail. These framesets feature the exact high-performance geometry ridden into the European pro peloton by legendary world-cup teams like Ijsboerke, Capri Sonne, and Tulip Computers. A standout premium feature of this frame is the beautifully executed internal brake cable routing through the top tube, keeping the bike's silhouette incredibly clean and aerodynamic. Unlike mass-produced frames of the era, Miyata handled their entire steel manufacturing completely in-house—even drawing their own steel tubes in proprietary raw material high-ovens. The frames were then precision-brazed by Japanese master builders, resulting in pristine lugwork, investment-cast dropouts, and a structural longevity that easily outclasses its Italian contemporaries.\u003c\/p\u003e\n\u003cp data-path-to-node=\"8\"\u003ePresented in its official factory-labeled size of 56 cm, this frameset features standard BSA threading, a 27.0 mm seatpost fit, and a clean clamp-on front derailleur interface. It is the definitive, bulletproof foundation for an elite period-correct restoration or a stunning high-end neo-retro build destined to stand out on any classic ride.\u003c\/p\u003e","brand":"Goldensteelcycles","offers":[{"title":"Default Title","offer_id":58468156080473,"sku":null,"price":659.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0805\/6609\/2121\/files\/frame-koga-miyata-pro_1.jpg?v=1783004138","url":"https:\/\/goldensteelcycles.com\/products\/koga-miyata-pro-vintage-steel-road-frameset-hardlite-spline-fm-1-triple-butted","provider":"Goldensteelcycles","version":"1.0","type":"link"}
