Description

This lugged steel frameset presents a dependable foundation for classic mechanical builds, manufactured during the high-utility era of French workshop production. Engineered specifically for standard 700C wheels, it incorporates classic tolerances and traditional metalwork designed to provide frame compliance and long-term durability on varied road surfaces.

Technical Integrity & Thread Standards

This secondhand steel frame has been weighed on site at 3390g including the fork, ensuring a robust wall thickness that handles typical riding vibrations. True to its heritage, the tubing carries its original finish. For restorers looking to configure a complete drivetrain, this chassis requires specific period-correct components. For alternative sizing from the same era, you can also view our Motobecane 700C 57x56cm frame or compare options with this Bazou steel frameset.

Please note that minor cosmetic storage wear, micro-scratches, or superficial aging may be present on this pre-owned part. The high-resolution photos form an essential part of the description, documenting the exact physical state of the lugs, alignments, and paintwork.
