It is a common, everyday double road crankset by Sugino. I just swapped the big chainwheel which I wanted to use, to the inside position so it would line up with the rear sprocket. The displaced small chainwheel, usually on the inside, was moved to the outside because the bolts holding them to the cranks are a certain length and I did not think they would work with the thickness of one chainwheel missing. I don't know why juggling chainwheel positions to help chain alignment is a radical idea, I doubt I am the first one to do it. But I am over 60 years old so may have seen a lot more things younger people have not is al I can figure.
