I just got a "pink" Koga-Miyata model ROAD-RACER. I can't founD anything about it... Anyone knows something about it??
And I am quite confused. I think it is from the late 70's. But no idea. It's serial number is: G690888. Any idea from when it is?? T-Mar??
The fact is that it's components are:
-Tubes: TANGE chamion chrom molibdenum.
-Front derailleur: Shimano 600
-Back derailleur: Shimano crane??? Any idea about it?? It is good?
-Wheels: Mavic(Champion du monde sur rute)
-Crank set: Dura-ace
Here is the bike:
