Hello! Brand new forum member here. I started a project recently to convert my 90's Fuji ATB to a single speed. I have found a tremendous amount of info on the Internet but one sticking point is my crank chainring. I have a spider that looks too small to bolt up most of the chainrings available. I have attached a photo of the bike and a close up of the crank. Would I be better off replacing the whole crankset? If I do, will I need a different BB? I would appreciate any help I can get. Thanks in advance!

You'll be fine with that crankset.

Figure out what the bolt circle diameter is by looking at the link and then order the appropriate sized chainring. You will probably be stuck with 3/32, but I don't think that will be a problem.

It is hard for me to figure out which BCD mine is. I guess I will have to measure it and try to convert to mm to get a close guess. Thanks for the reply!
