Still no justifiable link with derailleurs - but I liked the picture. To my relief, Peugeot have added a seat tube to their earlier design - but the bottom bracket is not at the junction of the seat tube and the down tube. The chain looks funky - and there is a weird object just in front of the chainwheel.
