I bought this Peugeot PY10 in Amsterdam from a shop called Willem’s vintage bikes. It was refurbished by Willem and it rides amazingly well and is very light and nimble. It’s basically a factory race bike and as is normal for the period it seems to be not exactly like other models of the same bike from the same era.
I’m guessing it was built in the late 70’s or early 80’s. Unique touches on this bike not on others of the same vintage include the pantographed fork crown and color matched saddle.
