Trek Frame Serial Numbers 1980 - 1981
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
1980 and 1981. In 1980 the serial numbers began with 000000 and ended
with 001130. Although not specified, we estimate the sequence began
in November of 1980. Nineteen eighty one began with 001131 and ended
with 010265. (The end date is actually not clearly marked in the original
list.) Each line represents a run and shows model number, frame size,
and a range of serial numbers.
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.
