I had one one these exactly the same except it was a blue main triangle (mine was a "comp" badged frame).
Mine was a 1999 frame, but think they used the same frame 1999-2000.
Look out for cracks in the chainstays around the "pipe" joining them together ahead of the wheel, mine cracked there and specialized replaced under warranty with a beefed up version.
I also had the same disc mount (AFAIK the disc mount only come on "enduro models of the same era, but could be bought separately direct) and an BETD travel upgrade link.
Decent bike for £200, definately not up to jump / freeride but a great XC bike - would be better with a modern pro pedal shock.
