So based on the info in the first post, my Japanese made Peugeot Canyon Express lugged mountain bike is an Araya built frame... serial number is stamped on the seat tube near the BB on the non drive side: ARYG556273. This would translate as Araya built, July ‘85, sequential frame # 56273. Correct? It is a lovely frame and currently undergoing a transformation into a 26” wheeled touring bike...
