It only takes a minute to sign up. This is a canonical question that will hopefully encompass all of the questions we get asking us to determine what year a bicycle was manufactured how old is my bike, how old is my frame, etc.

Each "answer" should address a different way to determine the manufacturing year of a bicycle. To some extent, these will also help you narrow down the model as well as it will tell you what distinguishing features to look at. Literature e. Cottered cranks vs square tapered or splined cranks and bottom brackets. Style of shifters brifters, triggers, etc. Frame tubing type e. Reynolds tubing introduced aroundstill used today; Reynolds tubing introduced around So a frame with an original decal can't be from the 70', decal doesn't help as much because of the range of years produced.

Also, see Decals. This applies only if decals are original or have been replaced with the identical design. Tubing decals Reynolds, Columbus, etc. Earlier bikes tended to have less fancy, less colorful, less quantity of decals. Headbadges: most early bikes had actual "badges", often quite detailed and fancy, made of metal, then plastic, and finally just using decals on the headtube. Most bikes lost their metal badges in the 60's and early 70's, although some brands still have actual badges to this day, but in general a real badge indicates an earlier model bike.

Cassette vs. Race bikes tended have less braze-ons the earlier the year of manufacture. By the 80's if it was clamp-on, it was a sign of very cheap models and most frames had braze-ons for all cables, with multiple bottle and accessory bosses depending on style and use. A previous owner could have replaced or upgraded components on a bicycle, so this guide only applies to original equipment. There is a delay between the introduction of a technology such as indexed shifting and when manufacturers start selling products that use it.

Low-end manufacturers may continue using technology that is severely outdated such as one-piece cranks, freewheels, or quill stems because it is cheaper to do so.

A number of bikes are built in a Retro style, but with modern components. Dutch bikes, trendy coffee cruisers, and beach cruisers may be modern but appear to be s styling. These tend to have modern rims and brakes as a giveaway. Note that bicycles. How much your bicycle is worth depends on the location of the buyer and seller, how much the buyer wants the bike, etc.

Bicycles except children's bicycles are almost always required to have a frame or serial number. Some manufacturers use a date-code as part of the serial number. Surly is another manufacturer who uses date codes, this time in their stamped frame numbers. However, many bicycle manufacturers don't use date codes and so you can't easily decode their serial numbers.

Some of these manufacturers will provide their own serial number lookups on their websites. Some of the other ones have been reverse-engineered by their rider communities. The best way to find out is to google " manufacturername bicycle serial number date of manufacturer. See also the Mongoose answer is below. I managed to date my old Raleigh by finding scans of old catalogues online.

That model was only sold in one particular year, but more often you'd get it to within a few years this way.It all began with a dream to design the lightest bicycle frame in the world.

The Rubicon Comp was released.If the bike frame was manufactured at the Santa Ana CA facility, the first three or four digits of the serial number should be letters abbreviating the model or size of the frame such as "XL", "XXL", CR24, or something like that.

The next part of the serial number is eight numeric digits. The first four numbers should be a two digit month followed by a two digit year. The last four digits are the serialization digits to depending on what number the frame was of the years production. If the frame was made overseas in Taiwan, it gets more complicated.

If the number starts with a K, the frame was made by Kinesis. RobinsonDynoPowerlite and Auburn included. The first digit would be a letter designating the factory that made the frame. There might also be a second letter digit specifying the factory that assembled the bike, if applicable.

The model and year of production was also coded by a letter, so you won't be able to spot a two digit month and two digit year. Before I left, I was writing a specification to standardize all of the serial numbers because GT was starting to send most of its US production to other US fabrication shops.

The information might also come in handy for deciphering other makes because the factories in Taiwan make bikes for a lot of different companies. I am tinkering around with the idea of starting to make my own frames, kind of on a "one-off" basis. I am also teaching welding at a local community college. By the way, did I tell you that the guy ran GT's in house fabrication for the last ten years he recently retired was none other than Gilbert Axt.

Do you remember Race, Inc.? That was Gilbert. History, man. It might be a really cool thing if I can track down Gilbert now and interview him for you. Michael S well we get a good bit of gt serials that could be identified by the owner, if they only had the tips that some of us have learned, so i will post what i know, and anyone with more knowledge can add to it.

M1 stands for "mach one" that is your model gt. Here is another example. C is the 3rd letter in the alphabet, and march is the 3rd month, so march is the build month.

KRASH 4 Click here for details on how to order your copy of the history of CCM. I was talking with Don Farmer yesterday.

He believes that for many years in the 60s that more than one Letter designator may have been used. Out of necessity, Dons memory is acute. From his experience over five decades of collecting bikes, he recalls that the following years and letters correspond to each other. He also suggests that the date on original SA 3 speed hubs is a good way to establish the date.

Contact me at bmwchev msn. With all due respect to Mr. Farmer and other distinguished members of the hobby, my experience tells me that even the best memories can become clouded over the years. Were would the only CCM Cobra fall? All known Cobras have an "A" serial number. I have never seen a or catalog, only a few individual advertisements. Lots of the CCM bikes changed slightly from year to year, even if it was in minute ways such as details to decals or parts.

My main interest is in the musclebikes from to and I compared data from over 50 of my bikes. Other similarly interested collectors agreed with my findings. Their serial numbers helped confirm my data from those years. Again, I do not mean to disrespect anybody, just encourage the sharing of actual visual or numeric data.

I totally respect your investigative skills and passion. A thought did come to mind as a result of this dialogue I am quite unfamiliar with Musclebikes Could there have been a sequence of serial s for the Muscle bikes separate from the mainstream?

Interesting question. The response from the younger collectors here certainly seems to reinforce ccmusclebike's reading of the numbers. I occassionally see people claimimg that there bikes are a specific age, when I know it's not possible. I usually just bite my tongue and carry on.

Sometimes I'll politely suggest a differnt age and supply catalog pictures to persuade them to change their info. My collection of serial numbers included my non-musclebikes, such as Imperials, Grand Tourings, Centennials, Elans, Rangers, Rebels and a few others that may have escaped my memory.

I would like to set up an online picture database, with numerous bicycles and written details such as c hainguard styles, decal styles and placements, mechanical details and of course suggested serial numbers. We'll get it sorted out efficiently, someday! When the letter code groups are plotted by sales year it quickly becomes apparent that the highest letter code in each year, starting with A-codes inadvance by one letter for each subsequent year.

The latest letter code is also, with one exception, the largest letter group for the year, with margins of up to The presence of old letter codes for a sales year are easily explained by leftover stock. The Targa was introduced in and that when it's first sales are logged and they are all E-codes.

I could site additional cases, but it would be superfluous. When the results of the letter code plotting is taken in conjunction with the results for new model introductions, the code system becomes virtually indisputable, at least for This, in conjunction with the recently documented G-codes, would mean that CCM used every letter from A though L during the period of to It's obvious that CCM using some form of multiple codes during the s.This is the fourth post in the series.

The date will help you find the correct decals for your bike and also help to figure out what your Haro BMX is worth if you are going to sell. I spent quite a bit of time looking into the Haro serial numbers on a few of my bikes as well as checking against other Haro BMX owners to see if my serial number crack was right. As with the other 3 cracks, this holds up too. Generally, the year was stamped as the first part of the serial number.

The serial number below can be read in the same way. July built bike.

how can i tell what model gt bicycle i got by the serial number?

This bike would be known as a model. See the month chart below. The example below is slightly different but still has the build year as a number in this case a 4. The just the year stamp remained - dropping the decade. Month possibly remaining as number also. CO - this was taken from a build Group 1. Month of build often after the year.

Into the 's once again the system changed slightly. However the basic structure remained the same. Frames were normally manufactured the year before being sold in bike shops.

So a build date on a frame of usually means the bike was sold in I might be able to help. Then upload a photo of your bike and the serial number. We'll take a look and try to help you out. Thanks for reading. Share Pin. Leave a comment Name Email. News RSS.
