Nice Jackson. Here is mine, made about 1990. I purchased it NOS to replace a frame that snapped on my commuter. Bars, stem, brakes, chainset, front derailleur, seat pin all come from the original Dyna Tech that I bought about 25 years ago! I do about 65% of my annual mileage on this, all the way from when the clocks change in Nov until about June when the best bike comes out of hibernation.

And before anybody says, yes, that is a low gear (39x27), it's hilly down here in Kent and I can't manage on a 39x23 like when I was 25 :chargrined:
