• Univega Serial Number Year Guidelines

The serial number is 'L334521'. Looking at the 1983 & 84 Miyata catalogs and what people elsewhere have posted here & there about this Univega model, it looks like the addition of lowrider mounts was part of the 1984 model year for Miyata and, at least on Univega, is found rarely on some, I assume late year production, 1983 models.

By Year/Model 1970's Redline Squareback First production bike was serial number 100. A low number bike would be early 1974. By the 500-600 range somewhere begin the 1975's.
