I was stoked to find this ‘89 Trimble Inverse 4 (serial # 150, out of ~450 ever made) recently, even if it needed a LOT of work. I’d been looking for one for ~15 years! The frame was sound with no cracks or general damage. In fact, the bike had seen relatively little use in it’s ~34 years of existence!
I’ve never spent as much time on a resto/build as I have on this one! Hours of frame prep for the respray, hours of internet trawling for parts, months of waiting for $#1t to arrive from all over the world & many hours in the workstand!… Very happy with the outcome though.
I deliberated on a few details, like the outer cable colour & some spec choices, as I wanted to keep the build absolutely as close to original/period-correct as I could, but in the end, I had to make some concessions.
