PEUGEOT PY10 PX10 frameset FULL REYNOLDS 531 58.5*57cm 3040g 125.4mm BSFF

This second-hand French road frameset constructed from legendary Reynolds 531 steel tubes presents an authentic restoration opportunity for classic cycling enthusiasts. Weighing in at 3040g, this Peugeot PY10 frame offers a highly regarded mechanical baseline, though it requires specific workshop attention before final assembly. The photos are part of the description and reveal the exact cosmetic condition and technical points detailed below.

Critical Mechanical Note & Threading Status

Prior to planning your build, observe that the threading on the right-hand side of the bottom bracket shell is damaged. To resolve this, you must either rethread the shell or install a specialized threadless Mavic emergency bottom bracket. Please note that the cup shown in our detailed images is solely there to illustrate this technical issue and is not included with the frame shipment. If you are also working on compact builds, you may want to compare this layout with our smaller Peugeot PY10 Reynolds 531 53.5x54cm frame.

Frame Dimensions & Geometry

Measurements are taken precise center-to-center for horizontal alignment, and center-to-top for the vertical tube:

• Seat tube (a): 58.5 cm (measured from center of bottom bracket shell to the top of the seat lug)
• Top tube (b): 57 cm (measured center-to-center)
• Rear spacing: 125.4 mm

For restorers who also maintain vintage French touring bikes, proper component matching is critical; we recommend browsing our authentic Mafac brake levers to complete your cockpit setups.
