Its the triple crankset that was on the original bike and as you can see theres no hex bolts holding the chainrings to the cranks, just what looks like rivets. The only way i can see to remove them is with a tool that fits the centre of the inside of the crank, other than that I am stuck. Is there a way to remove them or do i need to just buy a whole new cranket?
Ok so the chainset:
