These pics will give you an idea of what Peugeot was doing in the late 80's early 90's. This particular frame is a Cycleurope product so '92 at the earliest. Late 80's frames shared very similar design characteristics...no chainstay bridge, non-adjustable no name vertical drop outs, short BB/chainstay lug joints with small cut outs, fast back seat satys. Of note on this frame are the lug windows and lack of fork crown pantographing.
