Hand-me-down from a friend, who used it as his commute bike when he lived in San Francisco. Now he's into racing and even completed the Kona Ironman.
I don't know much about Nishiki Sport bikes but I think it's one from the 80's. A bit big for me so I keep the saddle down pretty low.
One month into a 6.5 mi each way commute. Been rewarding so far.
