Restoration Technical Notes
To ensure a flawless mechanical build, please note the technical specifics of this frame set. The included fork is non-original, with a steerer tube that measures approximately 5mm longer than the frame head tube. Achieving correct headset preload and eliminating play requires adding one or two washers during assembly. Additionally, the existing finish is prime for restoration, with a full repainting recommended to return this iconic machine to its former glory. The high-resolution product photographs constitute a fundamental component of this technical description.

FAQ
What headset is compatible with this Peugeot frame?
This frame features French thread standards. The fork has a 25X100 thread, meaning you will need a classic French-threaded headset. Ensure you add one or two washers to compensate for the 5mm extra steerer tube length.
What is the bottom bracket thread type?
The bottom bracket shell uses a 35x100 'French' thread. Standard British (BSA) or Italian cups will not thread into this bottom bracket shell.
Why does the fork need washers?
The included fork is non-original, and its steerer tube is approximately 5mm longer than the frame's head tube. Washers must be placed under the headset locknut to ensure correct, secure assembly.
Are there any structural cracks or frame damage?
No structural cracks, major rust, or frame bends are present. The frame is structurally sound, though the paintwork needs to be fully redone due to cosmetic wear.
