This was my Vista Elite, with a Sturmey S3X 3 speed fixed hub and left side drive. Budget brand Vista tried moving upmarket in the mid-70s with a very nice, light frame, probably made by Nishiki. The bike was originally sold with sew-ups and a 1st generation Dura Ace grupo.
It had been 30 years since I'd ridden fixed and back then the fixie was my daily ride. Much older, and with many other bikes to ride, I could not break myself of the habit of trying to stand and coast over potholes. So I traded it to a young neighbor for a season's worth of lawn mowing. But after 2 mows she moved away, taking the bike with her.
