Deciphering Klein S/N

Yes, they would have known about the coming specs but generally bikes made later in a year are called the following years model. So a a bike made in Nov. of 91 is generally sold as a 92. I bought my 2011 mukuk in Oct. of 2010. So the 92 Attitude is truly a 92 attitude made for 1992 components with a 1992 number of Annn. I'm not sure you're entirely correct on this (not saying I am either).

As far as hex goes, I don't find it likely. I don't know a single mechanical engineer who uses hex. Much more likely is an engineer who uses something like the size of the bike, the date of manufacture and a number (i.e. 20T1193821). That's not to say it isn't hex and so far it hasn't gone outside of the hex number (0-9 & A-F) just that I don't think of mechanical engineers using hex as a likely number base but may have had a computer guy whispering in his ear: "The answer to the world is 2A..2A!"

I used to dream of destroying worlds and evaporating continents...and my life has come to this: Serial numbers. I'm going to hunt a giraffe, I'll probably feel better.
 
Guess what kind of engineer I am, and I immediately went to HEX. I'll give you one hint, it's not computer engineering.

Also, there will always be exceptions to ever rule. Left over frames, etc... blah blah blah.
 
Start with serial numbers, move on to small appliance repair, and work up to destroyer of worlds

Here's my two cents:

One 1990 Attitude, KLEIN embossed HS seal, original paint, frame serial number is BAT501 and the serial number of the fork is 5A5D2:

One 1992 (or maybe 1991?) Attitude that's out for a repaint in HLF, serial number of the frame is AA3 and there's a MAG-21 fork in it:

Wow, no idea they made that many bikes per year.
I guess that dispells any idea that they are "rare".

They're not rare at all... just very expensive for some (unknown to me) reason. If you have 3000 USD burning a hole in your pocket, an Attitude or Adroit isn't hard to find at all ;-)
 
mine :
Picture of said bike :

Frame S/N (under BB or rear dropout) : BAT4BC
Fork S/N (on back of dropout) : I have to look…

Fot the year, I'm 99% sure it's a 1990 ;)

So your 1990 is a mid year model with the revised headtube, frame #1281 fork #1490

The XS looks to be a very late 1991 frame #2723

Correct, mid 1990 frame #1212
