The serial number list and the code for the list are not available from Trek (but hope springs eternal).In the meantime, we have the results of the serial number decoding project:). This letter may also have been used for custom 750 frames.If you know which mark was used by a particular craftsman, please let me know.The dates coded in the serial numbers, or the dates inferred from the numbers, are dates on which the new frames were stamped with serial numbers (serialized).Alternatively, the letter extends the range of the character from 0 to 9 (if a number) to 1 to 26. There is no Model 310 in the brochures on the site; however, a frame has been reported that has Ishiwata high tensile double butted main tubes with the SN A4F9H67. According the the SN, it apparently was made in June 1979, after the TX300 is no longer in the brochures, but no similar frame is listed.

It is likely these frames, SNs beginning with M or N (Models 41x and 61X), were contracted out or were made in a separate Trek facility, and were given the old serial number form so as not to interfere with the sequential numbers being assigned by Trek in their main shop, which began in late 1980.This variation to the SN system may have been done to extend the numbering system.By using the fourth character as an extension of the last three, the serial numbers could be extended from 2600 possible combinations to 26,000 for a given month. Serial numbers for four model 510 frames (with a leading F) have been reported that have similar unexpected year dates.These dates are not necessarily the same as the model year of the frame. I have included a photo of the results from my bike.At some time late in each year (beginning generally September or October) the frames produced were created from designs, and painted with colors, for the next year. In this case I used a red candle to make the serial number stand out.

In the case of some early 80s Treks, the number is under the plastic cable guide on the bottom of the shell.
