Trek Frame Serial Numbers 1983

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 that (mostly) took place in 1983. In 1983 the serial numbers began with 42925 and ended with 113648. Each line represents a run, and shows model number, frame size, a range of serial numbers, and the date on which the serial number was applied to the brazed frame. The serial numbers are not necessarily sequential in time. Some of the runs at the beginning of this table may have actually taken place in 1982.

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.

* NOTE: the run above originally was marked in the paper listing as Model 620. The 620 is marked through and "520" is entered above it. The "520" is in the same hand as the rest of the listings on that page. It is run 1419 and is marked with an asterisk. Above it are runs 1298 and 1299. The date on that line (the serialization date) is 7/12/83. Four pages later in the listing is where run 1419 should be. That line says "1419 - see page 29", referring to the earlier page. The line above, that has a date, is for run 1409, dated 10/5/83. That late in the year, it would be made as an 84 model.

A bike in the serial number range of run 1419 has been shown, by paint, graphics, and components, to be an 84 Model 620. This indicates that the run was as originally marked: Model 620. Also, it indicates that the date of serialization for the run was 10/5/83 or later, making them 84 models.
