Fuji Sports 10, red, 1978. trashed frame and probably the fork too.
serial 78B90230 = 1978 February Culver City California Zip Code.
Low end 10 speed. 6.5" cranks make it hard to ride up any grade. Mostly stock except bar pads, tires, rear brake caliper, rack.
Going to become a bar stool. The fork looks a bit off on the left side, noticeable when test riden. I'll put it on a fork gauge when dismantled. Some parts will be put in the parts bin (local bike coop).
