titanium mountain bike mongoose bike serial number

The top of the seatpost tube is not in the greatest condition either. The frame has a small nick in the headtube which would be covered by the headtube sticker and someone has also removed the rear brake bridge. It was originally red, and some of the original red epoxy is still visible, but the Supergoose used the same frame as the Team bikes did in 1980 and it could be built up as either. Please feel free to add to, or correct this post.Auction is for the vintage 1980 Mongoose Team/Supergoose frame pictured. The first digit was a letter followed by a one digit number F2 meant June of '82 (using the same code as the bike models above) and these SN's were no longer found on the BB shell, but rather the lug behind it.Īfter 1980 it gets fuzzy for me since I lose interest in mongeese after 1980. This continued until sometime after March of '81 when the SN just went to one line, dropping the top line completely. Later the 'T' was moved to the top line, in front of the 'C' for both Team Mongoose and Supergoose:

When the team mongoose model was introduced in '78, a 'T' was placed in a third row at the bottom, as shown in this pic (you can barely make it out, but it's there) The Racer-X models serial numbers started with an X (example: XB8, rather than CB8)

In early '76 a 'C' was added to the top line The earliest models ('75) were comprised of five digit numbers only (see pic) The next line was simply the sequentially numbered serial number. The third digit was the last number in the two digit year: The second digit was the letter code for whichever month the BB shell was manufactured: The first digit C stood for Chatsworth (California, where the factory started out) Typically, the Serial Number was on two lines, looking like this: (maker of Mongoose) used the same format for all of their bicycle brands (Jag, Roger DeCoster, Moto-Trac, etc.) with a few exceptions.
