Description

A direct artifact of mid-century French bicycle manufacturing, this André Leducq steel frame is engineered for authentic retro rebuilds. Built by hand, it delivers a rigid and balanced geometry optimized for 700c wheel setups and period-correct French-threaded components. Ideal for collectors and dedicated restorers seeking an uncompromised structural foundation.

Classic French Chassis Engineering

This classic lugged steel chassis measures 59.5 cm from the bottom bracket center to the top of the seat tube, with a 57 cm top tube (center to center). Built for durability, the bare frame assembly weighs exactly 2800g. It features standard vintage rear spacing of 121.4mm, accepting period-correct multi-speed hubs.
