    I know nothing about archery this just popped up on my feed, but is how does that pulley thing actually work? There’s a very stiff bow and then you get easier extension of the string with the pulleys - but what is the point of this instead of a just standard less stiff bow and normal string straight string?

    The center part looks very stiff, so I guess there’s less lateral flex for increased accuracy?

      I think you are talking about the Cams, which gives mechanical advantage, eg at the end of the draw cycle you are pulling back (and holding) only 75% (this is adjustable on some cams) of the 40 pounds of draw weight.

      Longer stiffer risers are more stable and more accurate. There is also a lot of physics involved with the limb angles etc. to absorb more vibration and shock, for quiter and more stable shots.
