Old Chameleon frame, big box section chain stays, horizontal dropouts with inserts held in with crank bolts to run gears and disk. Disk mount integral to frame not dangling down off the dropout insert like some I’ve seen.

Any ideas what year(s) this is from? Thank you.

And was it made in the U.S. of A?

Mine is the same description, I think it’s mk3.

Mine is a Taiwan made one though, I think it was 2005 or 2006 latest. So yours should be earlier than that.

Sounds like the first Taiwanese one, pre-EBB so 2001-2004 I think?

Thanks chaps. No EBB on mine so somewhere between 2001-2005 by the sound of it.

Mine has a date in the frame number, but it’s an American one.

Mine could have a date in the frame number Smmddyy48 in American date format. Is this the same format as yours Johnny?
