Trek Frame serial Numbers 1985

Prior to late 1980, Trek used an alphanumeric serial number scheme. Late in 1980, Trek changed to a sequential system, beginning with number 000001. The paper serial number list, provided by Trek, ending in 1986 with number 279975.

Given below is a listing of frame assembly runs for 1985. In 1985 the serial numbers began with 167779 and ended with 224106. Each line represents a run and shows model number, frame size, and a range of serial numbers. For some runs, the date the serial number was applied is given.

Frame sizes in the SN list below are as given on the paper copy. For some entries, only a two-digit number was given, the extra 1/2 or 3/4 inch was dropped. So - an entry of 22 inches really means a 22.5" frame size, 19 means 19.75", 25 means 25.5".

The table contains dates of frame serializing, and are not necessarily model year. At some time late in each year (generally September or October) frames were built for (then painted with colors for) the next model year.

  The above entry is from 1982. In 1982, Trek slipped three runs into the existing 82 serial numbers by adding a zero to the end of the serial numbers of the runs. Those numbers overlap with the numbers later used here in 1985. (Thanks to Mitch Hawker for this observation.)
