This is a Sugino Bionic crankset with the lopsided Biopace type chainrings.It is 170mm with 3 rings-28-38-48 all steel,so they wear like steel(,some, but not much) .It isn't very pretty, but it is fully functional.I think It came off a Hardrock, or maybe a Diamondback Ascent of early 90's vintage.The big ring bolt holes are ~64mm center to center(of closest ring, not the actual diameter-actual diameter is about 198mm x188mm on the big ring-top of tooth to top of tooth.All the rings are the lopsided type(biopace type)
