This second-hand Superator steel chassis provides a classic geometric foundation for collectors and mechanical restorers seeking to assemble an authentic mid-century road machine. Weighing in at 3265g, this vintage road bike frame displays the standard craftsmanship of its era, making it an excellent candidate for historic bicycle assemblies or retro randonneur-style setups.
Classic French Chassis Geometry & Integrity
Engineered for stability and endurance, the Superator features a seat tube measuring 58cm (measured from the bottom bracket center to the top of the tube) and a top tube of 57cm (measured center-to-center). It comes with a rear dropout spacing of 128mm, allowing compatibility with classic multi-speed vintage hubs. As a genuine second-hand component, the surface shows signs of age-appropriate wear; we highly recommend examining the high-resolution images closely, as these photos are part of the description showing the exact paint condition and decal preservation.
For restorers aiming to complete their steering assembly, pairing this frame with a period-correct 153mm steel bicycle fork or a matching 162mm steel bicycle fork will ensure compatibility with traditional French headtube standards.
