Here is an email I got from an actual employee of GT: 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 0000 to 9999 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.

Chion mondiale 19 you can see the piet de wit font is the same as on your gazelle gazelle bicycle miss grace. The 1974-1976 models are the easiest to date; almost all of these (with exception to some held-over '73 frames) simply follow the standardized serial system developed by Raleigh in mid-1973, whether Gazelle or Nottingham in origin: Seat tube will be stamped with two letters, followed by a series of 6 or 7 numbers - first.

That's the only one I remember off the top of my head. There were at least four companies in Taiwan that made the GT lines:,, and 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.

He also did the original PK Ripper for SE Racing. History, man. It might be a really cool thing if I can track down Gilbert now and interview him for you. THAT is the kind of stuff that belongs in the BMX Museum! I'll write you when I get a chance. Dan Garcia and here is the updates, thanks to love thegoose! (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.so here we go.

Here is an example to go. On the dropout you have 'M1' followed by '08922198'.this one is simple. M1 stands for 'mach one' that is your model gt. It can also be a 'I' for interceptor and so on. Sony Spectralayers Crack.

Next on the serial is '0892' this is easy to decode too, 08 means 8th month, which would be august. Then you have '92' next in the lineup, this would be 1992 the last 4 digits, are your build number, this one would be the 2,198th one built. Here is another example.

If your serial is KGCG2297 this one gets a little complicated. But still easy once you learn the code to it. The first letter is who made the frame itself, in this case it would be 'Kenisis', an overseas company.this could be replaced by another letter but at least we know what that one is there for.
