hey everyone. i have an old 1970s ross. Its a steel frame and It is starting to get some surface rust. I am sending it out to s+d powdercoating soon. After i get it back I plan on putting all new componants on it. I am looking for a new crankset. The frame has an american BMX style bb. Is there any modern cranksets that have 2 chainrings around. Also what was/is the size hub for these bikes. I am trying to make this a cheep rebuild. I just want a fun road bike I can ride around and not be anal about it getting banged around. I have an all original 1981 ross that is in prime condition and i love riding it, but it has a few small rust spots and dings. I dont want to get the condition any worse. Thanks for your help.
