Still trying to figure out who made the bars on these Norco's. Ritchey does seem to be the origin of the "high rise", but doesn't answer who made the quill version on the Norco's. I did dig up some info on Norco, and their connection with Nishiki/Sekai - https://mtbtimeline.com/wiki/norco/start Can't seem find Norco catalogs earlier than 1988 to see if they listed specs on bars
