The Miyata 610's banner years were from the mid-1980s when the lightweight steel frames made in Japan, and Shimano components were a bargain for a decent ride. I can attest to it's comfortable touring and road absorbing qualities.
There are lots of other beauties out there in various renditions, still ridden and loved. I wanted to share a few with you. If there are any that I've missed, send a photo and information and I'll add it here.
