This mid-century vintage steel touring bike frame represents a classic foundation for retro rando builds and high-mileage vintage setups. Engineered for 700C wheelsets, this chassis balances structural durability with standard touring geometry. The structural integrity is sound, featuring an integrated rear spacing of 117mm and a total bare weight of 3000g. Detailed photographs constitute the primary physical description of this second-hand item, illustrating its authentic cosmetic condition, patina, and original mechanical fittings.
Technical Geometry & Vintage Alignment
Designed for prolonged saddle time and stable handling under load, this vintage touring bike frame utilizes traditional lugged steel construction. The frame has been measured precisely from the bottom bracket center to the top of the seat tube (55cm), and center-to-center along the top tube (56cm). It includes a specific mechanical refinement: an additional securing bolt (visible in photo 12) designed to lock the down-tube gear shifter levers firmly in place, preventing slippage under high cable tension.
