Classic French Engineering: Peugeot PR10 Reynolds 531
This authentic 1970s French road frame is constructed with three main tubes of high-tensile Reynolds 531 steel, offering the classic compliance and responsiveness sought after by retro-cycling purists. Sized at 58 cm (seat tube, center-to-top) by 57 cm (top tube, center-to-center), this frameset is designed to accommodate traditional 700c wheelsets. It features classic French standards, including a 35x100 bottom bracket shell and a 25x100 threaded steer tube, making it an excellent platform for a period-correct build.
