Here's my 1984(?) Nishiki sport with no original parts. Serial number 4436267. Bought it here in Japan for more than it is probably worth, but frames anywhere in the ball park of my size are nearly impossible to find here so I grabbed it up. Looks like it was originally bought in Philadelphia.
A few pages back someone with the same frame was asking about converting it to 650B, and I have to say it works great. It has plenty of room for 42 mm Grand Bois tires and fenders. Maybe one of these winters I will try brazing on some canti studs.
Built with almost entirely spare parts I had sitting around, including a mutilated triple crank set up as an ultra compact double, Shimano dynamo hub, and Busch & Muller lights. Makes for a wonderful camping bike.
