Hi Forum people.
I have just bought a Koga Miyata Fullpro 1981 road bicycle with a serial number biginning with a letter J****** stand for 1981 the year of production. There is also a number including below: 585. Is this number standing for the frame meassure? Witch mean 58,5 cm?
There are also engraved the Letters DW-DD What do these letters stand for? DD probably stands for Dynamic Drive?
I think I also have a original team frame because on the gold head tube there is no badge but vertical standing ‘Koga Miyata’ and on the bottom of the top tube is also an eyelet for a race number. Maybe anyone can help me?
