Hi there still not sure what cranks they are, just to repeat do not, I repeat do not ride a bike without the crank nuts on to loosen as even minor movement will destroy your taper on your cranks, might not be noticable until you tighten it then an overtightened crank can develop cracks or just keeps coming loose. You can overtighen cranks too remember
