I'm fixing up an old Lotus Unique from 1986 or 7, I believe. Reasonably nice bike, it seems to me. Interestingly, according to the tubing stickers, the frame (maybe just the main triangle, it's not specified) is triple-butted Ishiwata EX, and the fork (obviously original) is Tange Mangaloy 2001. I've never seen a bike before with tubing from two different manufacturers. Does anyone know how common that was? Not important, just wondering.
By the way, the bike is huge--66 cm with a 36 inch standover, with the 28C tires I have on it now. I usually ride a 62 or 63, but I can JUST stand over it--touching the top tube but not really pressed against it. It's going to be interesting to ride--I've suffered with many bikes that were marginally too small (or way too small) but never one that bordered on being too big. First bike I've ever had where I can put the bars level with the seat.
