Still got mine, exactly the same year (1990) and it was my first MTB.
Since then I've done over 40,000 miles on her, everything broken or worn out except the frame. Nowadays she's dressed as a tourer with drop bars.
The best days ever were :
1 Crossing the Golden Gate bridge at sunset after having ridden from Portland Oregon
2 Riding the Slickrock trail
3 Bombing down a hill in Australia at 45mph with 4 panniers and a barbag
4 Using her as a daily commuter in Singapore.
Thanks for showing the photo - a realy treat as to what my bike once looked like. That grey Zolatone paint is soooooooo cool.
