Welcome to (mostly) mid-1991. Checked the SN# against the web resources available. The frame is circa 1991 with a 51xx SN#. That is the year I got my first decent MTB (a Trek 8000 bonded). My brother has that now. I'll get it back one day. Mark my words! Bwahahahaaa!
This steed has seen some use and has lots of cosmetic indicators, but all in all, it seems pretty nice. It has the small pressed BB (I hope that won't turn into a troublesome affair). It has Cook Bros cranks, lots of XTR, a Seven stem and Merlin Ti Bar, Syncros Ti seatpost. The fork is a White Brother and has holes for disc, so it is newer of course. I think he said the climbing handles were Titus..? (sound right?) Nuke Proof hubs.
I hope I didn't overspend. It was local so no shipping. It seemed so easy I couldn't resist. I think the headset needs replaced. It has a hairline crack. Enjoy the pics you enabling buggers you!!!
Awful flat test ride pedals removed. My buddy hang in out with me in the man cave.
