Also of note is the 'T' (for team), was also dropped. This applies to all frames made, EXCEPT those starting with the letter 'M' as these frames were made in the Merida factory in Taiwan.) As before, the letter indicates the month and the first number or the second digit in the sequence indicates the last number for that year. (nb: The frames were still made in Chatsworth up until 1984 when they moved to Moorpark. The 'C' was dropped and they started out with a single letter followed by a sequence of numbers. In April 1981 and onwards the frames were coded differently. (there are a couple of known Supergoose frames without the flat seat stay. NBB: In 1982 and onwards, a Team frame was also offered in 'Show Chrome' as well as red or blue candy coat.

As opposed to a candy coated full cromo frame = team frame. NB: a Supergoose is just a full cromo team frame that has nickel (79/80) or chrome plating (81 onwards) as its final finish. Very early team frames had a 'T' but without the flattened seat stay, but these are very few and were in 1977 mainly. This was done to give better clearance for the chain. (Moosegoose, Two/Four, Two/Six, and the Kos Krusier also have 100 % Chromoly tubing).Īnother feature of a Team / Supergoose frame is the flattened seat stay where the chain passes it. The Team Mongoose, Team Minigoose and Supergoose, all should have a T in this area. The same coding applies to the first part of the serial numbers as we discussed above, however, if a capital T is in front of or above the CXX it indicates that it is a 100% Chromoly frame.

The Team Mongoose and Supergoose frames are a little different. NB: Super X has an “X” instead of a “C” in the serial number. The rest of the serial numbers are sequential and are the number of frames produced in that series. The next number is the last number of the year the frame was produced. The next letter in the sequence is the month code. For example:Īgain, the C stands for Cromoly to make note of which frames were updated with Cromoly. Each frame had a combination of three key numbers or letters.
