Halcion days indeed. My MTB life ended somewhere around 1996 when girls / beer and cars suddenly became a whole lot more important than cross country racing through gorse bushes on a wet sunday morning. I didn't ride anything again for a good 10 years or more.
First 'proper' MTB was a Raleigh of some description, Suntour thumb shifters as I recall. It was far too big for me (bought off a mate) and despite what I recall as fantastically skinny tubing, probably weighed more than I did at the time.
Next up would have been a 1993 Giant Cadex CFM-3 and I'll be blowed if I can remember what happened to that, I think I sold it to fund the next purchase which was..
.. a 1995 Klein Fervor (pre-Trek) which I built up from the frame / forks / mission control stem using a mix of XT / XTR and raced for a local shop team for a couple of years until I faded out of riding all together.
At one point I sold it to a mate who then proceeded to leave it in his back garden for 3 years until I bought it back off him. I resurrected it about 3 years ago and did some MTB'ing on it but these days I'm a road rider for preference and the Klein was converted to single speed beach cruising / leisure rides with the wife and cycle plus train commuting duties.
Unfortunately the Mission Control stem/bar combo snapped due to fatigue and the frame as a whole is looking pretty battered these days as it's taken it's fair share of abuse over the years, and the BB is in a right state (not a simple fix as they're sealed klein units).
So yesterday it was dropped into my LBS as a bare frame for them to remove the BB and see if there's anything they can do with it, once it's out the frame will go off to the powder coaters for a blast and coating then it'll be put back together, and will I'm sure continue to give sterling service.
