TX700 frames were available as special order, with Columbus tubing instead of the specified Reynolds 531. However, this model did not appear in any of the Trek brochures on this site. Serial numbers beginning with M or N (41X and 61X bikes or frames) seem to have a different meaning for what normally is the year digit.

Just remove the plastic cable guide to see the number.

The other place Trek (or their subcontractors) stamped the SN is at the lower end of the seat tube.

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.

"Rub the area with candle wax of a color that contrasts with your paint. Note that even with the serial number filled with wax, the leading "0" is almost imperceptible."Before late 1980, Trek used an alphanumeric serial number scheme.

Another small mystery; for now we'll call it a 310.

One interesting variant of the SN code has been submitted.

On some bottom brackets there are two codes: one indicating the maker of the main triangle and the other for the maker of the rear triangle or perhaps the person who cut and shaped the tubing, if not done by the framebuilder.

If you know which mark was used by a particular craftsman, please let me know.

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.
