I just saved this Sekai Competition bicycle from our local metal scrap recycling center. A three dollar purchase. No wheels, but everything else looks to be original except for the seat. The frame has some minor chips here and there, but the stickers/decals are mint. Some specifications are:
Serial number 76B90059 on underside of bottom bracket
Tange Double-butted High Tensile Throughout tubing
Suntour GS dropouts
Suntour Cyclone derailleurs with Suntour Barcon shifters
Dia-Compe Deluxe black-anodized brakes
SR Forged handlebar stem
SR Road Champion/Sakae Custom handlebar
Sugino Maxy crankset
25.8 mm seatpost (made in Japan)
Any information about this bike would be much appreciated (e.g., model number, year).
Its fate is to be a single-speed for my daughter to complement my single-speed converted 1981 Panasonic Team bicycle that I purchased right out of college. A nice pair of relatively high quality Japanese rigs.
