Hello, i'm from Medellin, Colombia, i need some help to identify the year of my bike, it is a centurion Le mans RS with the red/white/red pattern with the original shimano light action group, i've searched for the serial number under the bottom bracket trying to identify its year model or fabrication but it doesn't coincide with the patterns that i found on the Sheldon Brown data, someone there that could help me a little? here is the serial number KL590995
