Mira move crank pulley's weight v's Zero under drive/ light crank Pulley

As ii says in the title I have weighed a Zero One under drive or lightened crank pulley to find out the difference’s in weight between the 2.
Please beware I went brain dead as soon as I started filming so you have to do your own maths.
In this I used a stock ed20 crank pulley I didnt do an ef/el crank pulley as I didnt have one to do the comparison.


584 grams :open_mouth: thats a fair difference
