Meticulously hand-brazed in Japan by Miyata's master craftsmen using double-butted Tange Champion chromium-molybdenum seamless steel tubing, the frame utilizes the reinforced 26.8 mm seat-tube wall configuration engineered to deliver exceptional lateral stiffness under power while preserving the sublime road-smoothing ride quality classic Japanese steel is renowned for. The frame is outfitted with forged Shimano SF vertical-entry rear dropouts complete with integrated tension adjuster screws, matching Miyata Cr-Mo fork blades with elegant crown detailing, a dependable 68 mm BSA bottom bracket shell, and traditional clamp-on derailleur compatibility. Finished in Koga’s distinguished metallic champagne green finish with contrasting period decals, this 56 cm frameset offers the quintessential base for an authentic, period-correct 6-speed Shimano 600 or Dura-Ace build.\u003c\/p\u003e","brand":"Goldensteelcycles","offers":[{"title":"Default Title","offer_id":59337399632217,"sku":null,"price":539.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0805\/6609\/2121\/files\/frame-koga-miyata-gents-racer-s-green_1.jpg?v=1788866712","url":"https:\/\/goldensteelcycles.com\/products\/koga-miyata-gentsracer-s-vintage-japanese-steel-frameset-tange-champion-cr-mo-1","provider":"Goldensteelcycles","version":"1.0","type":"link"}
