My '88/'89 (best guess based on components) Koga Miyata Randonneur. Not much on the webs about these. I haven't posted in the BF touring section, but a search brought up zero hits. Most of what I find is in German (which is where this bike is from originally) and mostly concerns the newer aluminum version.
Here's the rundown on mine:
Shimano 600 brakes
New Ultegra bar ends
Shimano 600 cranks (w/ biopace small and middle ring...I actually like 'em)
Shimano 'deer head' FD
Suntour XCD 6000 Accushift RD (I'd never seen this one before--it looks and functions great)
Shimano 105 hubs w/ Mavic M3cd rims
Just took it for a shakedown ride yesterday and it rode flawlessly.
