Hi,
Newcomer here. Rescued this bike from the scrappers truck yesterday. I believe it a Professional, Tange Champion #1 tubing. Suntour/Sekae/Sugino component mix. Looks like its all chromed under the black paint. No decals other than the faint remnant of the Professional and the Tange decals. Sweet bike, super light, but really little-maybe 49cm. Wish I was short. SN is M1A00752.
