I'm definitely replacing the cranks eventually as there are literally no 3 bolt chainrings available and I was wondering if these cranks would work if I removed all the chainrings and keep the 42t on. The rear cog is 16t so it would be about 70 gear inches and have 8 skid spots which is fine with me. I figure I could sell the extra chainrings as well if I need to. I'm not 100% sure what the BB spindle is, but if it's square tapered my plan should work, right?

EDIT: Here's a pic of the current cranks.
