Looks like Mid-70's Panasonic built. Those ride great. If'n you wish to lighten the wheelset ever, I have a bunch of aluminum 27er rims.My neighbor was tossing this to the curb. Caught him in the act and snagged it. Been in Storage for over 30 years. In perfect shape but hated the ride of it stock. Changed out the offending components and love it. Needs hybrid tread. Stock tires on it.View attachment 202879
Durability and ability to handle some dirt, Schwalbe HS-159. If you want to go fast on pavement or hardpan, Panaracer Pasela 27x1.
