Trek Body Serial Quantities Serial Amount Location Travel body serial amounts (SNs) are usually typically stamped into the bottom level of the underside bracket cover. In the situation of some earlier 80s Treks, the number will be under the plastic material cable manual on the base of the system. Just get rid of the plastic material cable guidebook to discover the number. The some other place Travel (or their subcontractors) stamped the SN is at the lower end of the chair tube. Take note: The SN on your authentic sales invoice may not really complement the one on your bicycle.

Sales individuals sometimes had difficulty reading through the quantities. Many early Trek bottom level bracket covers have a one or two letter code stamped individually from the seriaI number. This was made by the individual framebuilder to mark his/her function. On some bottom level mounting brackets there are two requirements: one suggesting the machine of the primary triangle and the various other for the creator of the back triangle or possibly the person who reduce and formed the tubing, if not really done by the framebuiIder. If you understand which mark was used by a specific craftsman, please let me know. Serialization Day The dates coded in the serial figures, or the times deduced from the amounts, are times on which the new frames had been stamped with serial quantities (serialized).

These times are not really necessarily the exact same as the model yr of the body. At some period past due in each season (starting generally September or October) the structures produced were created from styles, and decorated with colors, for the following season. Hard to read through? Travel serial quantities can be hard to read through.

Clear the region well, and make use of plenty of light at numerous angles. A recommendation by M. Hansen can assist you examine a serial number. Serial Number outlined with red wax. Click on picture to discover an enlarged edition. Hansen) 'Scrub the region with candle wax of a color that contrasts with your color.

Lightly clean it off with a rag. The polish remains in the indented region of the Beds/N.

Now you can effortlessly read the number. I have got included a picture of the outcomes from my bicycle. In this case I used a crimson candle to make the serial number remain out. Notice that actually with the serial number loaded with polish, the top '0' is nearly imperceptible.'

Serial Quantity Descriptions The serial number explanations are divided into five classes. Click on on the link below to go to the suitable category. PRIOR TO LATE 1980 Before late 1980, Travel utilized an alphanumeric serial number system. Each seven-charactér number consists óf three characters mixed with numbers. The serial number listing and the code for the listing are not obtainable from Trek (but wish springs timeless).

In the meantime, we possess the results of the serial number decoding project: Serial Quantity Decoding Project Nearly two hundred Trek owners posted their frame's details to help decode Travel's initial serial number system. Our thanks to these ample cyclists.

Travel utilized this program from 1976 to late 1980. A version of this first system had been utilized in 81 and perhaps 82 for some structures. See. season exceptions beneath. These serial numbers have got seven characters, in the type L N L In L N In, where M can be a notice and D will be a number. Right here are the outcomes: The very first letter is definitely the model designation. The notice code indicates frame model, which would include bike models made from that model of framework.

A = 310 (find notice. below) B = TX200 (observe be aware. below), C = Texas300, Deb = 530, Age = TX500, Y = 510 (. ), Gary the gadget guy = TX700 and TX770 (discover notice. below), L = 710, I = 730, J = Texas900. T = 910, L = 930, M = 412 and 414 (. ), D = 610, 613, and 614 (.

O = 950. This numbering program was utilized for custom 950s. This notice may furthermore have happen to be used for custom 750 frames. If you have got a leading O (Oh) seriaI number on á frame with Reynolds 531 peel off stickers, please contact me (Skip). This implements just to serial quantities in the type LNLNLNN where the initial letter is definitely an U (Oh). This does not use to the aIl-numeric serial numbér form that began in late 1980.

These start with a zero not an Oh. Fór these all-numéric figures with a top zero, find below. A couple of serial amounts have been posted that are usually missing the initial notice.

This notice designates the model. The remaining six heroes are standard.

It seems that some custom frames had been constructed that did not match within the standard model explanation. For example, a 710 frame produced with Columbus tubes instead of 531. What leading notice to make use of? Probably it had been just remaining empty?

The first number will be the body dimension, where 1 = 19.75', 2 = 21', 3 = 22.5', 4 = 24', 5 = 25.5', 6 = 57.5 cm (ctc) or shows a custom size. (Observe Year Exception Deb.) 7 = 59 cm (ctc) or indicates a custom dimension. (See Year Exception M.) 9 = 63.5 cm (ctc) or signifies a custom made size. (Find Year Exclusion M.) The 2nd letter represents the 30 days the body was serialized. December The second number is certainly the last digit of the calendar year, 6, 7, 8, 9 (for 197X) and 0 for 1980.,., for 12 months exceptions. Again, this is usually the day of serializing, not necessarily magic size season.

The final three personas - The last letter runs from A to Z and the finaI two numbers gó from 01 to 99. The final letter might become a run status, with the last two numerals the framework number in that run? Additionally, the notice extends the range of the character from 0 to 9 (if a number) to 1 to 26.

This gives a variety of 2600 for the 3 personas. Any various other concepts for these final three figures? The rest of the program code defines period to a month. Perhaps as soon as Trek had been nearing even more than 2600 bikes/frames of a given design per month, a fresh serial number structure needed to be developed.

Hence the change to the sequential system that was began in late 1980. Records:. There is no Model 310 in the leaflets on the web site; however, a body has become documented that offers Ishiwata higher tensile twice butted major tubes with the SN A4F9H67. It has touring duration chainstays. According the the SN, it apparently was produced in August 1979, after the TX300 can be no longer in the brochures, but no equivalent frame is listed. Another small mystery; for right now we'll call it a 310. One fascinating version of the SN code has become posted.

It provides a top B and provides eight personas rather of the usual 7 (B4K6B109). It offers SunTour dropouts, and experienced a partial tubing label that included the text message 'Stress BUTTED'. The date from the SN is definitely Nov. Most likely a TX200 with an additional personality in the SN. Various structures with a top serial notice of Gary the gadget guy have long been reported with Columbus tubing stickers. Texas700 frames were obtainable as particular order, with Columbus tubing instead of the chosen Reynolds 531. These bikes were designated as Design Texas770.

Nevertheless, this design did not really show up in any of the Travel leaflets on this web site. Year Exclusions: A new. Serial amounts beginning with Meters or D (41X and 61X bikes or structures) appear to possess a various significance for what normally is the yr number. The year digit is usually the 4th personality in the numbér. In the 50 M and In serial numbers that have got been sent in by owners, the yr numbers proceed from 0 through 9. The staying part of the serial figures seem normal.

Regarding to the leaflets, Trek do not make 41X and 61X bicycles or structures during 76, 77, 78, and 79 and furthermore not really in 83, 84, 85, 86, 87, 88, or 89. These serial numbers apparently do not follow the 12 months convention utilized for various other Trek versions. It is certainly most likely these frames, SNs starting with Michael or D (Versions 41x and 61X), had been developed out or were made in a distinct Trek facility, and were given the previous serial number form so as not to intervene with the sequential numbers being assigned by Trek in their main shop, which began in past due 1980. This variation to the SN program may have been performed to lengthen the numbering system.

By using the 4th character as an expansion of the last three, the serial amounts could end up being extended from 2600 achievable combos to 26,000 for a provided 30 days. For Meters and In top serial quantities, if the TREK letters on the seattube have no colorwrap behind, the bike is certainly from 1980 or perhaps 1981. If it provides a colorwrap, the bicycle is probably from 1982.

Serial quantities for four model 510 frames (with a leading N) have been reported that have similar unexpected year schedules. (Our thanks to Full Ferguson, Fred Goméz, and Chris Container.) The fourth characters are usually 2, 3, 4, and 5, there may end up being more.

The structures have got the earlier TREK images on the seattube. These structures may end up being related to the Michael and N top serial number bikes in the section above. One earlier TX700 (top G), an assessment frame sent to a bike shop, got a 4 in the 12 months digit. Another difficult year code. This 4 may symbolize an assessment unit. Trek used this type of serial number (leading O 'oh') for théir custom-made 950 frames.

Trek Bicycle Serial Number Database

The creation (non-custom) structures had been numbered using the late 1980 to 1986 program described beneath. Three (leading U) 950 frames have happen to be documented that contain unlikely year rules of 5, 6 and 7.

Model 950 structures were not made in 1975, 76, or 77, but only in 1980, 81, or 82, (according to the leaflets). Another 950 frame was reported with a 0 (zero) in the season code, but had been decorated as a 1982. From the geometries, they all show up to end up being custom frames. When a Trek frame was repainted by Trek, an extra set of numerals was often placed into the underside bracket to indicate the frame was repainted. These amounts were usually four numbers, in the form NNNN.

LATE 1980 TO Later 1986 Later in 1980, Travel changed to a brand-new numbering program for their frames built in the U.Beds. The frames had been numbered sequentially, starting with number 000001. The record of the set up runs was documented in a handwritten diary. Trek (Kevin Tita) carefully provided a copy of the paper for this internet site. The list ended in Nov of 1986 with number 279975.

This serial number system actually prolonged through at minimum 1997 (observe Desk II below). The diary includes operate number, model number, framework size, and serial number range. Incidental info, including schedules and comments on the structures, appears erratically through the newspaper. A 'work' had been for a specific frame dimension and body model. We all owe thanks to Luker White colored who generously donated his time to transform very much of the paper list to digital form. These information were mined to generate bike creation by model for each diary yr. The results can become seen on the page. Jan garbarek.

Click on the date hyperlink in Desk I below to move to the comprehensive serial number info for that 12 months. Desk I - 1980 to 1986. In otes for Table I:. Table I consists of schedules of body serializing, and are not necessarily model calendar year. At some period past due in each 12 months (usually September or October) structures were built for (then coated with colors for) the following model yr. This newspaper information is usually summarized by year in Table We.

The 12 months designations in the table are approximate; not all of the works are usually sequential in time. This may end up being a outcome of subcontracting some framework manufacture.

For some years, the model number provided may be the lowest number (or an X00 number) for a series of versions that have got the exact same framework. For example, a 1981 body appearing on the listing as a Design 610 could possess been built into either á 613, 614, or 616 bike. Some of the Design 170 serial numbers are usually 6 numbers but perform not stick to the statistical series.

A upcoming task is certainly to type 170 numbers. Some of these are usually displayed in the 83, 84 hyperlink at the bottom of the table. Some early and middle 80s base brackets were proclaimed with 58TSI or 60TSI. In the early 1980s Tim S i9000.

Isaac designed new lugs and a new bottom group layer for Trek. The fresh bottom bracket shell will be typically ski slopes with 58TSI (or more seldom, 60TSI). This status is not part of the seriaI number but is definitely a design number of the shell. The TSI are usually Tim'h initials. The 58 or 60 refer to the position between the séattube and the downtubé. Some frames in this time period have a top 'A' before thé 6 digit number.

This may become more prevalent on lower degree versions. The 'A' may not really be part of the SN. Simply overlook it when searching up the numbér in the dining tables below. Body Sizes in the SN list below are usually as provided on the paper duplicate.

For some posts, just a two-digit number had been given, the extra 1/2 or 3/4 in . was dropped. So - an entry of 22 in .

really means a 22.5' body size, 19 means 19.75', 25 methods 25.5'. The list has two main gaps, matching to missing pages. Page 9 finishes with SN 027870 and the following page begins with 029118. Web page 61 finishes with 210065 and the next page starts with 215226. The SN checklist for 1986 has some serial number varies with observation about POs (buy purchases) to 'Merida'. These are usually for Model 800, 830 and 850 mountain bikes and Model 300 street bicycles.

These had been made past due in the year, so they possibly were all 1987 models. At minimum some of these were supplied to Travel as 'frames just'. One documented SN in these runs, for an 850, had been prefaced by the characters TML. From thé serial number checklist, the number of Trek structures or bicycles produced by Merida late in 86 totaled at least 8251.

Merida is a Taiwanese bicycle business that has been established in 1972. It is currently a major, worldwide participant in the bicycle business. See for info on this corporation. Past due 1986 to 1999+ This 6 digit (7 number starting in 1993) code prolonged into at least 1999, at least for some models (usually middle to top level and made in the Us all). The number máy or may not have got a leading zero, producing the six digits into seven numbers prior to 1993. The design is not really available for these figures but the yr can be motivated or approximated from Table II below. The info in the desk is usually from serial quantities submitted by site site visitors.

Our thanks to them. In comparison to the serial number schedules in Desk I over, the decades in Table II represent design years, not really the day the serial number had been applied. Table II - Model Years 1987 to 1999. 2290083 FOREIGN-BUILT Structures AND Bicycles AFTER 1982. Three various serial number forms have been posted for 1983 Trek Model 400 structures. One, proclaimed 'produced in Asia', start with JS adopted by six numerals.

The SN was situated on the bottom level of the bottom level bracket. A 2nd serial number is usually 81765.

Relating to the Trék-provided SN checklist, this corresponds to a 22' (22.5') Design 400 body made in 1983. This SN type is definitely for frames/bikes made in the Us all The number was designated on the bottom part of the bottom part group. The 3rd number is usually 403300950, which shows foreign built, but the country of origin sticker has been missing. This number has been runs at the underside of the straight down tube. It is most likely this 400 had been made by the same manufacturer as the 1984 bikes explained in the páragraph below.

For thé 1983 Design 400, it appears Trek used three resources for their structures or total bikes. Various 1984 Trek 460s, 420s and 400s have been documented with 9 digit numeric serial numbers placed on the lower seat tube instead of on the underside of the bottom bracket. These structures, or comprehensive bikes, evidently were produced in Japan by an outside service provider. The numbers submitted are in the variety of 401000000 to 440000000. An 8 or 9 character alphanumeric code was utilized for mid- and low-level structures subcontracted in Taiwan. Many of these bikes were labeled 'Made in Taiwan' (although the label often can be easily eliminated).

Trek Serial Number Decoder

This type of serial number shows up to possess been used during the period 1987 to 93. The number leads with a T (for Travel?) then a numeral, one notice or two, after that five (occasionally 4) numbers.

Sean Hickey recommended the very first numeral is the calendar year of manufacture, and the letter is certainly the month of the season (A - D). This is confirmed by serial amounts that were posted by additional Trek proprietors. If there are usually two words after the calendar year numeral, the first is certainly the 30 days. The second operates from A through at minimum Y. It might become a method of extending the 5 digit number series by a aspect of 26. A afterwards 8 and after that 9 personality alphanumeric SN structure, used starting in about 1989, also starts with a T (for Trek?). These later T quantities were utilized on lower level subcontracted structures but perform not follow the 2nn and 3rd or 3rchemical and 4th personality date meanings above.

Starting in about 1993 (design year 94), an 8 personality alphanumeric code was utilized for some bicycles. It starts with H and another letter (age.h. GN, GQ, GR, GS, GU, GV, GW, GY ánd GZ).

These are followed either by: 6 numbers, or a numeraI and a notice adopted by four numerals. The 1st numeral in thé SN may end up being the 12 months of serialization. JAZZ BY Travel Jazz will be a series of foreign-buiIt, entry-level bicycles that Trek sold in the early 90s. (Notice the for a little bit more info and thé for a 93 collection). There appears to be at minimum three serial numbér types:.

A FIipside model got the serial number JT0116 stamped on the bottom part bracket covering. Tabel persamaan ic. The JT probably appears for 'Jazz' and 'Travel'. The quantities may end up being the sequential frame number, starting at 0001. The 2nd type is a 10-character serial number. The first two figures are letters which are adopted by eight amounts. Examples are JT09010099 and FI08003231. A Latitude design offers a 10-digit, all-numeric serial number:.

This number furthermore was rubber-stamped on the base of the underside bracket layer. These three serial number types may imply that Travel utilized at least three subcontractors fór the Jazz series. MISSING SERIAL Amounts A few proprietors of early Treks, mostly, from 1976 through the earlier 80s, survey their structures are not really noted with serial figures.

A prior Trek employee composed that the police in the Madisón and the surrounding area mentioned TREK has been popular for bikes with no serial numbers. Seems 100s didn't get any figures at all. Thé serial number guy just skipped a several?

Three some other opportunities: 1. In the early years Trek allowed, and actually motivated, their employees to use company equipment and materials to create personal frames after hours. These frames often had been not really serialized. The exercise ceased after creation was elevated, ensuing in little obtainable down period for the devices. The serial numbér on a répainted body that had been not very first stripped, may vanish under the fresh paint. The number can be under the plastic cable information attached to the bottom part of the bottom level bracket shell.Trek is a trademark of Trek Bicycle Corporation, Waterloo, WI AIl copyrights in thé TREK pamphlets, pricelists, proprietor's manuals and pictures displayed on this site are usually the sole property of Travel Bicycle Corporation, Waterloo, Wisconsin.

My Travel 520 is certainly rainforest natural also and it is definitely a 2004. That is certainly the only year I understand of that Travel manufactured 520't that colour. As of a few yrs prior it had been slate grey.

If it is usually new enough to possess V-brakes I'd state it'h safe to state it's i9000 relitively brand-new, this is usually a rare function on street bikes and wasn'testosterone levels common technology until the late 90'h. Serial number Bull crap 6102. I'michael not sure that the serial number system mentioned on this site implements, the second notice (Beds), would not really use to a month of the yr. I hope this helps you.
