The 13 - 14.5mm shaft does not bend, it does give some flex in the engine on high revs but it will not bend. The 5mm SG shaft can be tested to roll the crank on the edge (crankwall over the edge) of a flat surface with a right spacer under the tip of the 5mm shaft. When rolling the end tip must not wobble over the spacer.
