My first bike after move to Japan. Picked up an old 520 Cro-MO frame by Tsunoda - Grand Prix , minimal rust and decent paint. It had some old Suntour VX derailleurs, aluminum-far-too-narrow drop bar with suicide brakes, Sugino 165 cranks, lowbar Shimano friction shifters, Araya 27x1.25 aluminum rims (close to true) and a freewheel 6 speed -Suntour - 125mm rear end.
I decided for now to go with the original wheels (new tires, tape and tubes - repack bearings & replace rear axle), but swap the old freewheel for a new Shimano 7. front derailleur to Sora double, rear derailleur to Tiagra RD-4601 (10 speed), keep friction shift for now, replace handlebar, breaks Tektro Long.
So here is the part that I am very interested in hearing from people about; I wanted to work with the bike for a while, get a good feel before settling on a handset (this will be the biggest cost and from what I can tell the most constrained decision)which includes deciding to change wheels or build a new rear 27 to go with modern 10 speed index shift or get a handset to work with the 7 speed or what?
