This ALAN is the Competition model (judged by the way the stays attach), probably from the late seventies/very early 80's because of the lack of cable guides. The gold colour is awesome! All ALAN's use 25 mm stems. Originally many of these bikes came equipped with Campy Nuovo Gran Sport, at least my competition did.

OT: The difference between the competition model and the Super Record (the most common types) is that the seat stay attachment and the SR has stiffer (thicker) tubing. They also have less pantographing on them on the lugs, forks etc. for most phases of production.
