Vintage Schwinn Bike Serial Numbers Location
Trek Frame Serial Numbers (Draft) Serial Number LocationTrek frame serial numbers (SNs) are typically stampedinto the bottom of the bottom bracket shell. In the case of some early80s Treks, the number is under the plastic cable guide on thebottom of the shell. Just remove the plastic cable guide to see thenumber. The other place Trek (or their subcontractors) stamped the SNis at the lower end of the seat tube.Note: The SN on your original sales receipt may notmatch the one on your bike. Sales persons sometimes had difficulty readingthe numbers.Many Trek bottom bracket shells have a one or two lettercode stamped separately from the serial number. This was made by theindividual framebuilder to mark his/her work.
If you know which markwas used by a particular craftsman, please let me know.Serialization DateThe dates coded in the serial numbers, or the datesinferred from the numbers, are dates on which the new frames were stampedwith serial numbers (serialized). These dates are not necessarilythe same as the model year of the frame. At some time late in eachyear (beginning generally September or October) the frames producedwere created from designs, and painted with colors, for the next year.Hard to read?Trek serial numbers can be hard to read. Clean the areawell, and use lots of light at various angles. A suggestion by J.

Hansen)'Rub the area with candle wax of a color that contrastswith your paint. Lightly wipe it off with a rag. The wax stays in theindented area of the S/N. Now you can easily read the number.
I haveincluded a photo of the results from my bike. In this case I used ared candle to make the serial number stand out. Note that even withthe serial number filled with wax, the leading '0' is almostimperceptible.' Serial Number DescriptionsThe serial number descriptions are divided into fivecategories. Click on the link below to go to the appropriate category. PRIOR TO LATE 1980Before late 1980, Trek used an alphanumeric serial numberscheme.

Each seven-character number consists of three letters mixedwith numerals. The serial number list and the code for the list arenot available from Trek (but hope springs eternal). In the meantime,we have the results of the serial number decoding project:Serial Number Decoding ProjectNearly two hundred Trek owners submitted theirframe's specifics to help decode the serial number system usedfrom 1976 to late 1980. DecThe second number is the last digit of theyear, 6, 7, 8, 9 (for 197X) and 0 for 1980.,.,for year exceptions. Again, thisis the date of serializing, not necessarily model year.The last three characters - The final letterranges from A to Z and the final two numbers go from 01 to 99.The last letter might be a run designation, with the last twonumerals the frame number in that run? Alternatively, the letterextends the range of the character from 0 to 9 (if a number) to1 to 26.
This gives a range of 2600 for the 3 characters. Anyother ideas for these last three characters?The rest of the code defines time to a month.Perhaps once Trek was nearing more than 2600 bikes/frames of agiven model per month, a new serial number scheme needed to bedeveloped.
Hence the change to the sequential system started inlate 1980.Notes:. Thereis no Model 210 in the brochures on the site; however, fourframes have been reported with a SN leading with an 'A'.Two had Ishiwata high tensile double butted main tube stickers,the other two were unmarked. They have touring length chainstays(one was measured at 44.5 cm) and the rear dropouts are withoutadjusters. According the the SNs, they were made after the TX200was no longer in the brochures. Another small mystery; for nowwe'll call it a 210. (Note: These frames previously were speculatedto be 310s.
However, without adjusters, as was the model TX200,they more likely were called 210s. One interestingvariant of the SN code has been submitted.
It has a leadingB and has eight characters instead of the usual 7 (B4K6B109).It has SunTour dropouts, and had a partial tubing sticker thatincluded the text 'TENSION BUTTED'. The date fromthe SN is Nov. Probably a TX200 with an extra characterin the SN. Severalframes with a leading serial letter of G have been reportedwith Columbus tubing stickers. TX700 frames were available asspecial order, with Columbus tubing instead of the specifiedReynolds 531. These bikes were designated as Model TX770. YearExceptions:A.
Serial numbers beginning with M orN (41X and 61X bikes or frames) seem to have a different meaningfor what normally is the year digit. The year digit is the fourthcharacter in the number. In the 50 M and N serial numbers thathave been sent in by owners, the year numbers go from 0 through9.
The remaining part of the serial numbers seem normal.According to the brochures, Trek did not make41X and 61X bikes or frames during 76, 77, 78, and 79 and alsonot in 83, 84, 85, 86, 87, 88, or 89. These serial numbers apparentlydo not follow the year convention used for other Trek models.It is likely these frames, SNs beginning with M or N (Models41x and 61X), were contracted out, and were given the old serialnumber form so as not to interfere with the sequential numbersbeing assigned by Trek in their shop, which began in late 1980.This variation to the SN system may have beendone to extend the numbering system. By using the fourth characteras an extension of the last three, the serial numbers couldbe extended from 2600 possible combinations to 26,000 for agiven month.For M and N leading serial numbers, if the TREKletters on the seattube have no colorwrap behind, the bike isfrom 1980 or perhaps 1981. If it has a colorwrap, the bike isprobably from 1982.B. One early TX700, an evaluation framesent to a bike shop, had a 4 in the year digit. That 4 may signifyan evaluation unit.C. Three 950 frames have been reportedthat contain unlikely year codes of 5, 6 and 7.
It is very unlikelythey were made in 1975, 76, or 77, more likely (from the brochures)1980, 81, or 82. Another 950 frame was reported with a 0 inthe year code, but was painted as a 1982. From the geometries,they probably were custom frames.
Trek apparently used a differentcoding method for these frames, perhaps so as not to interferewith the production frame serial numbers.When a Trek frame was repainted by Trek, an additionalset of numerals was often stamped into the bottom bracket to indicatethe frame was repainted. These numbers were usually four digits,in the form NNNN.LATE1980 TO LATE 1986Late in 1980, Trek changed to a new numbering systemfor their frames built in the U.S. The frames were numbered sequentially,beginning with number 000001. The record of the assembly runs was documentedin a handwritten journal. Trek (Kevin Tita) graciously provided a copyof the journal for this web site. The list ended in November of 1986with number 279975.
This serial number system actually extended throughat least 1997 (see Table II below).The journal includes run number, model number, framesize, and serial number range. Incidental information, including datesand comments on the frames, appears sporadically through the journal.A 'run' was for a particular frame size and frame model.We all owe thanks to Luker White whogenerously donated his time to convert much of the paper list to digitalform.Click on the date linkin Table I below to go to the detailed serial number information forthat year.Table I - 1980 to 1986. N otes for Table I:.
Table I contains dates of frame serializing, andare not necessarily model year. At some time late in each year(generally September or October) frames were built for (then paintedwith colors for) the next model year. This journal information issummarized by year in Table I. The year designations in the tableare approximate; not all of the runs are sequential in time. Thismay be a result of subcontracting some frame fabrication.
For some years, the model number given may be thelowest number (or an X00 number) for a series of models that havethe same frame. For example, a 1981 frame appearing on the list asa Model 610 could have been built into either a 613, 614, or 616 bike. Some of the Model 170 serial numbers are 6 digitsbut do not follow the numerical sequence.
A future task is to sort170 numbers. Some of these are presented in the 83, 84 linkat the bottom of the table. Some early and mid 80s bottom brackets were markedwith 58TSI or 60TSI. In the early 1980s Tim S. Isaac designed newlugs and a new bottom bracket shell for Trek. The new bottom bracketshell is typically marked with 58TSI (or more rarely, 60TSI).
Thisdesignation is not part of the serial number but is a model numberof the shell. The TSI are Tim's initials.
The 58 or 60 refer to theangle between the seattube and the downtube. Some frames in this period have a leading 'A'before the 6 digit number. This may be more prevalent on lower levelmodels.
The 'A' may not be part of the SN. Just disregardit when looking up the number in the tables below.

Frame Sizes in the SN list below are as given onthe 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 inchesreally means a 22.5' frame size, 19 means 19.75', 25 means25.5'. The list has two major gaps, corresponding to missingpages. Page 9 ends with SN 027870 and the next page starts with 029118.Page 61 ends with 210065 and the next page starts with 215226. The SN list for 1986 has some serial number rangeswith annotations about POs (purchase orders) to 'Merida'.These are for Model 800, 830 and 850 mountain bikes and Model 300road bikes. These were made late in the year, so they probably wereall 1987 models.
At least some of these were provided to Trek as 'framesonly'. One reported SN in these ranges, for an 850, was prefacedby the letters TML. From the serial number list, the number of Trekframes or bikes made by Merida late in 86 totaled at least 8251.Merida is a Taiwanese bike company that wasestablished in 1972. It is currently a major, worldwide player inthe bicycle business.
Seefor information on this company. LATE 1986 to 1997+This 6 digit (7 digit beginning in 1993) code extendedinto at least 1997, at least for some models (generally mid to upperlevel and made in the U.S.).
The number may or may not have a leadingzero, making the six digits into seven digits prior to 1993. The modelis not available for these numbers but the year can be determined orestimated from Table II below. The information in the table is fromserial numbers submitted by site visitors. Our thanks to them. In contrastto the serial number dates in Table I above, the years in Table IIrepresent model years, not the date the serial number was applied.Table II - Model Years 1987 to1997.
FGHIJTrek 2002 4300 had no final letter in SNJAZZ BY TREKJazz is a line of foreign-built, entry-level bicyclesthat Trek sold in the early 90s. (See the for a bit more info and the for a 93 catalog). There seems to be at least three serialnumber types:. A Flipside model had the serial number JT0116 stamped on the bottombracket shell.
The JT probably stands for 'Jazz' and 'Trek'.The numbers may be the sequential frame number, beginning at 0001. The exorcist 1973 full movie in hindi dubbed download. The second type is a 10-character serial number. The first two charactersare letters which are followed by eight numbers. Examples are JT09010099and FI08003231.
A Latitude model has a 10-digit, all-numeric serial number:.This number also was stamped on the bottom of the bottom bracket shell.These three serial number forms may mean that Trek used at least threesubcontractors for the Jazz line. MISSING SERIAL NUMBERSA few owners of earlyTreks, mostly, from 1976 through the early 80s, report their framesare not marked with serial numbers. A past Trek employee wrote thatthe police in the Madison and the surrounding area said TREK was famousfor bikes with no serial numbers. Seems hundreds didn't get any numbersat all.
The serial number guy just missed a few?Three other possibilities:1. In the early years Trek allowed, and even encouraged, their workersto use company equipment and materials to build personal frames afterhours. These frames often were not serialized. The practice stoppedafter production was increased, resulting in little available down timefor the equipment. The serial number on a repainted frame that wasnot first stripped, may disappear under the new paint.3.
