I just picked up a Raleigh Technium with a 6013 T6 frame which dates it around 1986. However, It is not a 420, 440 or 460. On the top tube it is called a Discovery. It has all the typical other markings that the 420-440 and 460 had. This is not a mountain Bike, but a road bike. I can not find any reference of Raleigh USA every building a model called "Discovery" Also on a sticker on the downtube near the bottom bracket it says "This is a sample bike and not to be offered for resale" It appears to be a factory sticker.
Do I have a proto-type...or was this offered to shop owners for display during that time period.
Would love any information about the Technium between 84 and 86 when the aluminum frame was in development. Also I can not find a serial number anywhere on the thing----Tom
