I was given a nice looking steel bike, the only labels are Hattori and Up Sports. It has nice Nito Olympiad bars and a Sun Tour deraileur, cool looking pedals but not sure what they are. In fact, I have never seen one of these. I have googled Hattori and they are the Japanese manufacturer of Williers (now being ridden in the TDF and Giro Italia, etc.) The frame says ultralight, and the down tube and seat tube are aero. No ideas on this bike, but would like any help.
