Handcrafted vintage bicycle frame 3120g 56×57cm 121.2mm

Restoring a classic road bicycle requires an authentic chassis engineered with historical precision. This hand-built vintage bicycle frame represents the golden era of European cycling craftsmanship, offering a robust foundation for classic retro-cycling builds. Weighing exactly 3120g, this lugged steel frame has been calibrated to deliver structural integrity and authentic riding characteristics. The original geometry features a 56cm seat tube paired with a 57cm top tube, measured from center to center.

Technical Specifications & Standards

Equipped with traditional standards, this frame is designed to receive period-correct vintage French parts. The bottom bracket shell is threaded to 35x100 "French" standards, which is essential for mounting vintage French cranksets. The fork steering column is threaded at 25X100, accepting matched traditional headsets. To ensure full compatibility with your restoration project, pair this chassis with components such as our classic Vintage Steel Moustache Handlebars or complete your rolling chassis with other vintage items from our collection.
