I recently mangled the toeclips on my 1984 Peugeot PX10 or PRO10, and am looking for replacements.
According to a catalog page I found, this bike came with Maillard 700 pedals. The pedals are marked Maillard CXC but I haven't found any identifying marks on the toeclips. The strap is Christophe but as I recall, the toeclips aren't.
The toeclip design is apparently unique: As you can see in the photo, instead of a plate that attaches to the leading edge of the pedal with a couple of bolts, it has a straight tongue that extends back under the foot. If these are sized, I would think they're size medium.
If you have a pair, or know of a source, please let me know.
