However, an MBA review of the 1989 Nishiki ATB lineup shows that year's Backroads to use rear cantilever brakes and have the down tube logo with the Cunningham Design designation, at least in the USA market. This is consistent with other 1989 Nishiki ATBs that have surfaced. The Canadian market models were still using U-brakes in 1989 but there was no Backroads model in Canada that year.
You’re right it really must be “G”. When I zoom in as far as I can, and compare it to my own Giant manufactured Colorado it has to be G.
It has Sugino cranks and Suntour Derailleurs And thumb shifters. Cycloid Chainrings. Araya 1.50 rims and Joytech hubs. A Steel handlebar.
Maybe there was a demand for another batch of the old model? It was originally sold in Newhall, CA.
