I found a bike on craigslist. He says its a mid '80s Sekai and it says "1000" and "Sports Series" on it. He also says its a 7speed (so i assume 7 in the rear so a 14 spd?) and has Shimano RX700 "drivetrain and brakes".
Supposedly its clean and working great and has a new rear wheel and bottom bracket. Think its any good? He's asking $200 for it, which is a bit steep in my book.
